  Reactions of per-O-acetylglucosyl isothiocyanate with carbon bases. A new method for the stereocontrolled syntheses of nucleosides and glucosylaminothiophenes

  摘要：

  Reaction of 2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosylisothiocyanate 5 with diethyl malonate in a basic medium gave the corresponding glucopyranosyl thioamide without significant deacetylation. This thioamide in solution presents Z-anti as the sole configuration. Reactions of 5 with carbanions which have an ethoxycarbonyl group are a way to prepare anomerically pure N-nucleoside derivatives of pyrrole and tetrahydropyridine. Reactions of 5 with carbanions stabilized by one cyano group are used to prepare glucosylamino thiophenes with only the B-configuration. Some other stereochemical aspects of the prepared compounds are discussed. (C) 1998 Elsevier Science Ltd. All rights reserved.
