Description

[0001] This application is a divisional application of the following application: application date November 30, 2022; application number 202280074056.4; invention title: "Compound containing cycloalkyl or haloalkyl".

[0002] Cross-reference to related applications

[0003] This application claims the priority and benefits of the following Chinese patent applications filed with the China National Intellectual Property Administration, the disclosures of which are incorporated herein by reference in their entirety:

[0004] Chinese Patent Application No. 202111441498.1 filed on November 30, 2021;

[0005] Chinese Patent Application No. 202111638379.5 filed on December 29, 2021;

[0006] Chinese Patent Application No. 202210564004.7 filed on May 23, 2022;

[0007] Chinese Patent Application No. 202210889925.0 filed on July 27, 2022; and

[0008] Chinese Patent Application No. 202211492694.6 filed on November 25, 2022. Technical field

[0009] This application relates to compounds containing cycloalkyl or haloalkyl, and specifically discloses compounds represented by formula I", their stereoisomers or pharmaceutically acceptable salts thereof, methods for their preparation, pharmaceutical compositions containing the compounds, and their use in the treatment of tumors. Background art

[0010] EGFR (epidermal growth factor receptor)-TKI (tyrosine kinase inhibitor), as a small molecule inhibitor, competitively binds to EGFR through endogenous ligands, inhibits the activation of tyrosine kinase, thereby blocking the EGFR signaling pathway, and ultimately produces a series of biological effects such as inhibiting the proliferation and metastasis of tumor cells and promoting apoptosis of tumor cells, and is one of the main targets for the treatment of lung cancer.

[0011] Osimertinib (Osimertinib, AZD9291) is a third-generation EGFR-TKI targeted drug. Although it has a high response rate to the drug resistance caused by the T790M mutation, patients will also develop drug resistance. According to the existing research on the drug resistance analysis of AZD9291, obtaining a third mutation, namely the EGFR C797S mutation, is one of the main mechanisms leading to the drug resistance of Osimertinib, accounting for about 40%. It has important research significance to provide a safer and more effective fourth-generation EGFR C797S / T790M inhibitor for patients. Summary of the Invention

[0199] Definition

[0200] Unless otherwise specified, the following terms used in this application have the following meanings. A particular term should not be considered indefinite or unclear without a special definition, but should be understood according to its ordinary meaning in the art. When a trade name appears herein, it is intended to refer to the corresponding commodity or its active ingredient.

[0201] The term "substituted" means that any one or more hydrogen atoms on a particular atom are replaced by a substituent, provided that the valence state of the particular atom is normal and the resulting compound is stable. When the substituent is oxo (i.e., =O), it means that two hydrogen atoms are replaced, and oxo does not occur on an aromatic group.

[0202] The term "optionally" or "optionally" means that the subsequent described event or situation may or may not occur, and this description includes the occurrence and non-occurrence of the described event or situation. For example, "optionally" substituted by a halogen for ethyl means that ethyl can be unsubstituted (CH 2 CH 3 ), monosubstituted (such as CH 2 CH 2 F), polysubstituted (such as CHFCH 2 F, CH 2 CHF 2 , etc.) or fully substituted (CF 2 CF 3 ). Those skilled in the art will understand that for any group containing one or more substituents, no substitution or substitution pattern that is spatially impossible to exist and / or cannot be synthesized will be introduced.

[0203] In some embodiments, the "one or more" described in this application is selected from one, two, three, four, five, or six. In some embodiments, the "one or more" is selected from one, two, or three. In some embodiments, the "one or more" is selected from one, or two.

[0204] C m-n herein means that this part has an integer number of carbon atoms within a given range, and any carbon present in the substituents of this part is not included in the m to n carbons of C m-n . For example, "C 1-6 " means that the group can have 1 carbon atom, 2 carbon atoms, 3 carbon atoms, 4 carbon atoms, 5 carbon atoms, or 6 carbon atoms.

[0205] When any variable (such as R) appears more than once in the composition or structure of a compound, its definition in each case is independent. Thus, for example, if a group is substituted by 2 Rs, each R has an independent option.

[0206] When the number of a linking group is 0, such as -(CH 2 ) 0 -, it means that the linking group is a covalent single bond.

[0207] When one of the variables is selected from a single bond, it means that the two groups it connects are directly linked.

[0208] When a substituent's bond cross-links to two atoms on a ring, this substituent can bond to any atom on this ring. For example, the structural unit means that it can be substituted at any position on cyclohexyl or cyclohexadiene.

[0209] means that the substituent is connected to other structures. For example, when the heterocyclic alkyl of R 1 is selected from , it means is connected to L:

[0210] The term "halo" or "halogen" refers to fluorine, chlorine, bromine, and iodine. When a group in this application has a halogenated group, the number of halogenations is optionally selected from one or more. In some embodiments, the "one or more" in this application is selected from one, two, three, four, five, or six. In some embodiments, the "one or more" is selected from one, two, or three.

[0232] The term "pharmaceutically acceptable" pertains to those compounds, materials, compositions and / or dosage forms that, within the scope of sound medical judgment, are suitable for use in contact with the tissues of humans and animals without excessive toxicity, irritation, allergic response or other problems or complications, commensurate with a reasonable benefit / risk ratio.

Tritiation (i.e., 3 H) and carbon-14 (i.e., 14 C) isotopes are particularly preferred due to their ease of preparation and detectability. Positron-emitting isotopes, such as 15 O, 13 N, 11 C, and 18 F can be used in positron emission tomography (PET) studies to determine substrate occupancy.
