AI Technical Summary
Existing methods for preparing 1-O-glycosyl carbamates require pre-conversion of the glycosyl or amino moiety, which is cumbersome, involves unstable reagents, is difficult to separate and purify, has low reaction efficiency, and makes it difficult to control the stereoconfiguration of the 1-position of the glycosyl group in the product.

Abstract
Description
Technical Field
[0001] This invention relates to the field of chemical synthesis technology, and more specifically to a method for preparing 1-O-glycosylcarbamate compounds. Background Technology
[0002] 1-O-glycosyl carbamates are a class of compounds formed by linking the nitrogen atom of an amino group to the oxygen atom at the 1-position of a sugar via a carbonyl group. These compounds can be considered glycosylated products of amines. The 1-O-glycosyl carbamate structure can be hydrolyzed in vivo by glycosidases, releasing the precursor amine. This modification can significantly improve the water solubility and bioavailability of amine drugs, thus giving these compounds broad application value in the fields of biomedicine and chemical biology.
[0003] Currently, there are three main reported methods for preparing 1-O-glycosylcarbamates. The first method uses 1-O-glycosyl-p-nitrophenyl carbonate as the glycosylation reagent (Bioorganic & Medicinal Chemistry 2017, 25, 5692-5708) and condenses it with various amines. The disadvantage of this method is that it requires the prior preparation of the glycosylation reagent, a 1-O-glycosyl-p-nitrophenyl carbonate compound. This reagent is unstable, difficult to store for long periods, and difficult to separate and purify. Furthermore, the product is a mixture of two isomers (α / β-) at the 1-position of the glycosyl group, making it difficult to control the stereoselectivity of the glycosylation reaction. The second method first converts the amino group to an isocyanate, and then condenses it with the glycosylation reagent to obtain 1-O-glycosylcarbamate (Carbohydrate Research). The first method (1998, 305, 341-349) is only applicable to primary amine substrates, requires the amine to be converted to isocyanate beforehand, and it is difficult to control the stereoselectivity of the glycosylation reaction. The third method uses glycosyl sulfoxide glycoside as a donor and Boc-protected primary amines to undergo glycosylation under the action of an acidic promoter, followed by tert-butyl cleavage to obtain the product (Synthesis 2013, 45, 27–39). This method 1) requires the amino group to be converted to tert-aminomethyl tert-butyl ester before the reaction can proceed, and 2) the reaction system contains a strong electrophilic reagent (trifluoromethanesulfonic anhydride), which is incompatible with the amino group. This method cannot achieve one-step direct glycosylation modification of amines.
[0004] Kyung Woon Jung et al. reported a method for synthesizing carbamates at room temperature via a three-component coupling reaction of amines, carbon dioxide, and haloalkanes in a polar aprotic solvent, in the presence of a base and with the promotion of tetrabutylammonium iodide (TBAI) (J. Org. Chem. 2001, 66, 1035-1037; Tetrahedron, 2002, 58, 3329-3347). The authors demonstrated through detailed control experiments that the key to the success of the reaction lies in the additive TBAI, which may play a role in converting inert chloroalkanes and bromoalkanes into reactive iodoalkanes via halogen exchange reactions before participating in the reaction. Daniel Riemer et al. reported a method for synthesizing carbamates at room temperature using a three-component coupling reaction of amines, carbon dioxide, and halogenated hydrocarbons (ChemSusChem 2016, 9, 1916-1920). However, the applicability of halogenated hydrocarbons in this type of method is limited to highly reactive halogenated hydrocarbons such as primary alkyl iodides, benzyl bromide, and carbonyl α-bromines. Coupling reactions of less reactive secondary alkyl halides and chlorinated compounds at room temperature have not been reported. This reaction imposes strict restrictions on the structure of haloalkanes and presents several challenges: 1) As a special class of electrophiles, the reactivity of haloglycosides is closely related to various factors, including the type of substituent on the sugar ring, the type of halogen atom, the type of nucleophile reacting with it, and the degree of reactivity matching between the nucleophile and electrophile. This makes it difficult to accurately predict the reaction results of haloglycosides with various types of nucleophiles, compared to alkyl halides (see Org. Lett. 2015, 17, 11, 2836–2839); 2) As a class of chiral compounds, sugars exhibit anomeric stereoselectivity in substitution reactions between their corresponding haloglycosides and oxygen nucleophiles. Certain types of haloglycosides can undergo specific S-reactions with specific types of oxygen nucleophiles under alkaline conditions. N Type 2 substitution reactions yield products with inverted configurations. However, for other types of halogenated glycosides reacting with oxygen nucleophiles under alkaline conditions, the products are highly dependent on the reaction conditions, yielding a mixture of two angiomeric epimers of the sugar ring (Russian Chemical Bulletin, International Edition, Vol. 65, No. 11, pp. 2776-2778). Furthermore, the nucleophilic reactivity of carbamates relative to halogenated glycosides is unknown, making it difficult to predict their anomeric stereoselectivity in reaction with halogenated glycosides. 3) Nucleophilic substitution reactions between halogenated glycosides and oxygen nucleophiles under alkaline conditions, even if strictly following the S... NType II substitution reactions yield products with inverted configurations. However, due to the potential for haloglycosides to undergo halide-catalyzed isomerization under certain reaction conditions (J. Am. Chem. Soc. 1975, 97, 14, 4056–4062), a mixture of two haloglycosides with different activities is obtained, making it difficult to accurately predict the stereoselectivity of the reaction. In summary, achieving the stereoselective synthesis of 1-O-glycosylcarbamates via a triplet coupling reaction using amines, carbon dioxide, and haloglycosides presents significant challenges and uncertainties. There is an urgent need in this field to develop simpler, more efficient methods for preparing 1-O-glycosylcarbamates with a wider substrate range and higher stereoselectivity. Summary of the Invention

[0641] The experimental results show that the two glycosylation modification products of Crizotinib—peracetylglucosylation modification product 3-85 and glucosylation modification product 4-1—exhibit good inhibitory activity against tumor cells HEK-293T, SK-MEL-28, and SNU-5. The inhibitory activity of peracetylglucosylation modification product 3-85 against tumor cells HEK-293T and SK-MEL-28 is comparable to that of Crizotinib and superior to that of glucosylation modification product 4-1. The inhibitory activity of peracetylglucosylation modification products 3-85 and glucosylation modification product 4-1 against tumor cells SNU-5 is comparable to that of Crizotinib. This indicates that the two glycosylation modification products can release the original drug through intracellular degradation. The glycosylation modification strategy adopted by this method can indeed play the role of a prodrug, and the inhibitory activity of peracetylglucosylation modification product 3-85 against tumor cells HEK-293T and SK-MEL-28 is superior to that of glucosylation modification product 4-1.
