Detailed Description Definitions Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this presently described subject matter belongs. The definitions provided below are intended to supplement and illustrate, not preclude, the definitions that would be apparent to one of ordinary skill in the art upon review of the present disclosure. Unless otherwise stated, the moieties described below are optionally substituted, i.e., they may be substituted at one or more positions. The terms substituted, whether preceded by the term “optionally” or not, and substituent, as used herein, refer to the ability to change one or more functional groups for another functional group or groups on a molecule, provided that the valency of all atoms is maintained. When more than one position in any given structure may be substituted with more than one substituent selected from a specified group, the substituent may be either the same or different at every position. The substituents also may be further substituted (e.g., an aryl group substituent may have another substituent off it, such as another aryl group, which is further substituted at one or more positions). When the term “independently selected” is used, the substituents being referred to (e.g., R groups, such as groups R1, R2, and the like, or variables, such as “m” and “n”), can be identical or different. For example, both R1and R2can be substituted alkyls, or R1can be hydrogen and R2can be a substituted alkyl, and the like. The terms “a,” “an,” or “a(n),” when used in reference to a group of substituents herein, mean at least one. For example, where a compound is substituted with “an” alkyl or aryl, the compound is optionally substituted with at least one alkyl and / or at least one aryl. Moreover, where a moiety is substituted with an R substituent, the group may be referred to as “R-substituted.” Where a moiety is R-substituted, the moiety is substituted with at least one R substituent and each R substituent is optionally different. A named “R” or group will generally have the structure that is recognized in the art as corresponding to a group having that name, unless specified otherwise herein. For the purposes of illustration, certain representative “R” groups as set forth above are defined below. Descriptions of compounds of the present disclosure are limited by principles of chemical bonding known to those skilled in the art. Accordingly, where a group may be substituted by one or more of a number of substituents, such substitutions are selected so as to comply with principles of chemical bonding and to give compounds which are not inherently unstable and / or would be known to one of ordinary skill in the art as likely to be unstable under ambient conditions, such as aqueous, neutral, and several known physiological conditions. For example, a heterocycloalkyl or heteroaryl is attached to the remainder of the molecule via a ring heteroatom in compliance with principles of chemical bonding known to those skilled in the art thereby avoiding inherently unstable compounds. Unless otherwise explicitly defined, a “substituent group,” as used herein, includes a functional group selected from one or more of the following moieties, which are defined herein. The term hydrocarbon, as used herein, refers to any chemical group comprising hydrogen and carbon. The hydrocarbon may be substituted or unsubstituted. As would be known to one skilled in the art, all valences must be satisfied in making any substitutions. The hydrocarbon may be unsaturated, saturated, branched, unbranched, cyclic, polycyclic, or heterocyclic. Illustrative hydrocarbons are further defined herein below and include, for example, methyl, ethyl, n-propyl, isopropyl, cyclopropyl, ally 1, vinyl, n-butyl, tert-butyl, ethynyl, cyclohexyl, and the like. The term “alkyl” by itself or as part of another substituent, means, unless otherwise stated, a straight (i.e., unbranched) or branched chain, acyclic or cyclic saturated hydrocarbon group, or combination thereof, and can include di- and multivalent groups, having the number of carbon atoms designated (e.g., C1-C10 means one to ten carbons, including 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 carbons).

These salts may be prepared by methods known to those skilled in art. Also included are base addition salts such as sodium, potassium, calcium, ammonium, organic amino, or magnesium salt, or a similar salt. When compounds of the present disclosure contain relatively basic functionalities, acid addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired acid, either neat or m a suitable inert solvent or by ion exchange. Examples of acceptable acid addition salts include those derived from inorganic acids like hydrochloric, hydrobromic, nitric, carbonic, monohydrogencarbonic, phosphoric, monohydrogenphosphoric, dihydrogenphosphoric, sulfuric, monohydrogensulfuric, hydriodic, or phosphorous acids and the like, as well as the salts derived organic acids like acetic, propionic, isobutyric, maleic, malonic, benzoic, succinic, suberic, fumaric, lactic, mandelic, phthalic, benzenesulfonic, p-tolylsulfonic, citric, tartaric, methanesulfonic, and the like.

The term “protecting group” refers to chemical moieties that block some or all reactive moieties of a compound and prevent such moieties from participating in chemical reactions until the protective group is removed, for example, those moieties listed and described in T. W. Greene, P.G.M. Wuts, Protective Groups in Organic Synthesis, 3rd ed. John Wiley & Sons (1999). It may be advantageous, where different protecting groups are employed, that each (different) protective group be removable by a different means. Protective groups that are cleaved under totally disparate reaction conditions allow differential removal of such protecting groups. For example, protective groups can be removed by acid, base, and hydrogenolysis. Groups such as trityl, dimethoxytrityl, acetal and tert-butyldimethylsilyl are acid labile and may be used to protect carboxy and hydroxy reactive moieties in the presence of amino groups protected with Cbz groups, which are removable by hydrogenolysis, and Fmoc groups, which are base labile. Carboxylic acid and hydroxy reactive moieties may be blocked with base labile groups such as, without limitation, methyl, ethyl, and acetyl in the presence of amines blocked with acid labile groups such as tert-butyl carbamate or with carbamates that are both acid and base stable but hydrolytically removable. Carboxylic acid and hydroxy reactive moieties may also be blocked with hydrolytically removable protective groups such as the benzyl group, while amine groups capable of hydrogen bonding with acids may be blocked with base labile groups such as Fmoc. Carboxylic acid reactive moieties may be blocked with oxidatively-removable protective groups such as 2,4- dimethoxybenzyl, while co existing amino groups may be blocked with fluoride labile silyl carbamates. Allyl blocking groups are useful in the presence of acid- and base-protecting groups since the former are stable and can be subsequently removed by metal or pi-acid catalysts. For example, an allyl-blocked carboxylic acid can be deprotected with a palladium(O)-catalyzed reaction in the presence of acid labile t-butyl carbamate or base-labile acetate amine protecting groups. Yet another form of protecting group is a resin to which a compound or intermediate may be attached. As long as the residue is attached to the resin, that functional group is blocked and cannot react. Once released from the resin, the functional group is available to react.

The present invention further provides processes for the preparation of compounds of structural Formula I as defined above. In some cases, the order of carrying out the foregoing reaction schemes may be varied to facilitate the reaction or to avoid unwanted reaction products. The following examples are provided for the purpose of illustration only and are not to be construed as limitations on the disclosed invention. Scheme A As illustrated in Scheme A, in general, compounds of the invention can be prepared by reacting substituted cyclic amines (B) using base such as DIEA or inorganic base such as K2CO3or Cs2CO3 to afford intermediate A-2. Intermediate A-2 can be converted to corresponding acid A-3 by treating A-2 with base such as KOH in aqueous EtOH or MeOH. Intermediates A-4, A-5 and A-7 can be formed either by treating A-3 and amine C, utilizing amide coupling conditions or by activation of appropriately functionalized carboxylic acid A-3 with (COCl)2or POCl3and with amine C base such as DIEA or pyridine in DCM. Intermediate A-4 can be prepared directly by treating A-2 and amine C in presence of Me3Al and toluene as a solvent. The compounds of formula A-4 and A-5 are independently treated with ammonium carbonate and PIDA in methanol to deliver compound of formula A-6. The compounds of formula A-6 can also be formed from intermediate A-7 by removing a protecting group, such as Boc under acidic conditions. Scheme B As illustrated in Scheme B, in general, compounds of the invention can be prepared by activation of appropriately functionalized carboxylic acid A-3 in dioxane with either (COC1)2or SOCl2 followed by addition of NH4OH to afford B-1. Intermediate B-1 can then be brought together with materials of variously substituted Br compounds, utilizing Xantphos-Pd-G2 mediated coupling conditions to deliver intermediate A-4 and A-7. The compounds of formula A-4 treated with ammonium carbonate and PIDA in methanol to deliver compound of formula A-6. The compounds of formula A-6 can also be formed from intermediate A-7 by removing a protecting group, such as Boc under acidic conditions. Scheme C
[0040] As further illustrated in Scheme C, in general, compounds of the invention can be prepared by derivatization of compounds of formula A-6 with R3 or R’ substituents. Acylation of A-6 with an activated acid such as an acid chloride and TEA followed by removal of any protecting groups would provide compounds of formula A-8 or A-9. When A-8 or A-9 are an N- acylated sulfoximine, the carbonyl group may be reduced with borane to a methylene group (CH2) to provide the corresponding N-alkyl derivative. Alternatively, N-alkyl derivatives may be obtained by alkylation with an alkyl halide such as, but not limited to, methyl iodide and a base such as diisopropylethylamineor Pd mediated coupling of A-6 with alkyl boronic acids.
