Preparation method for D, L-phenylglycine and analogue thereof

The invention provides a preparation method for D, L-phenylglycine and an analogue thereof. According to the method, benzaldehyde, an analogue thereof and hydrocyanic acid are adopted as raw materials and subjected to cyanidation reaction, and then 2-hydroxy-benzyl cyanide or 2-hydroxy-benzyl cyanide analogue (cyanohydrin for short) is generated. Cyanohydrin reacts with carbon dioxide and the aqueous solution of ammonia, and then 5-phenyl-hydantoin and an analogue thereof (hydantoin for short) are generated. hydantoin is successively subjected to steam stripping, alkaline hydrolysis, steam stripping, decolorization, neutralization, crystallization, washing, centrifuging, drying and the like to obtain D, L-phenylglycine and the analogue thereof. Compared with the prior art, the preparation method for D, L-phenylglycine and the analogue thereof can significantly and effectively reduce the pollution, and fewer inorganic salt by-products are generated. Meanwhile, the prepared D, L-phenylglycine and the analogue thereof are high in product yield and high in purity. Counted in benzaldehyde and the analogue thereof, the yield of D, L-phenylglycine and the analogue thereof is larger than or equal to 96%, and the product purity is larger than or equal to 99%. Meanwhile, the process flow is simple and feasible, so that the method is worthy of market popularization and application.

The design and synthesis of novel SGLT2 inhibitors: C-glycosides with benzyltriazolopyridinone and phenylhydantoin as the aglycone moieties

The sodium glucose co-transporter 2 (SGLT2) has received considerable attention in recent years as a target for the treatment of type 2 diabetes mellitus. This report describes the design, synthesis and structure-activity relationship (SAR) of C-glycosides with benzyltriazolopyridinone and phenylhydantoin as the aglycone moieties as novel SGLT2 inhibitors. Compounds 5p and 33b demonstrated high potency in inhibiting SGLT2 and high selectivity against SGLT1. The in vitro ADMET properties of these compounds will also be discussed.

Highly efficient dialkylphosphate-mediated syntheses of hydantoins and a bicyclohydantoin under solvent-free conditions

Diversely substituted hydantoins have been synthesized by new strategy from cyanamide based precursor, that is, methyl N-cyano-N-alkyl/arylaminoacetate. Dialkylphosphates were employed as the mild reagent to hydrolyze and cyclize the substrate in one step to give quantitative yields of the desired products. Syntheses of multivalent hydantoins viz bis-hydantoin, bicyclohydantoin have potentially widened the scope and applicability of the present method. Solvent-free conditions and very easy work-up procedure make the reaction convenient and eco-friendly. Single crystal structures of some of the representative compounds are also reported.
