  Efficient Syntheses of β-Cyanosugars Using Glycosyl Iodides Derived from Per-O-silylated Mono- and Disaccharides

  摘要：

  [GRAPHICS]Reported herein is a general method for the efficient syntheses of a variety of beta -cyano glycosides through the activation of per-O-trimethylsllyl glycosides with TMSI to form alpha -glycosyl iodides, which undergo S(N)2-type displacement when treated with tetrabutylammonium cyanide. The cyanoglycosides were reduced under mild conditions using NaBH4 in the presence of catalytic CoCl2(H2O)(6) in THF/H2O to give the corresponding aminomethyl glycosides.

  Synthesis of new 2-amino-2-C-D-glycosyl-acetonitriles in a Strecker reaction from various C-glycosyl aldehydes, chiral amines, and HCN was carried out. While aminonitriles from glycal and 2-deoxy-beta-D-glycosyl aldehydes were prepared in satisfactory yields, lower yields were obtained with C-glycosyl aldehydes. Strecker reaction with the benzyl-protected 1-C-formyl-D-galactal and S- or R-1-phenylethylamine (S-PEA or R-PEA) yielded predominantly the R-configured C-glycosyl aminoacetonitrile. The direction of the nucleophilic addition appears to be governed by the configuration of the anomeric carbon with beta-linked sugars. Since the stereochemistry of the transition state is unknown according to the configuration of the major product a Felkin-Ahn selectivity can be mainly presumed. (C) 2011 Elsevier Ltd.
