Four carbasugars, 5a-carba-b-D-manno-, a-D-allo-, b-L-taloand a-L-gulopyranose pentaacetates, have been prepared in a stereodivergent manner from D-mannose. Alkynyl derivatives of 2,3:4,6-di-O-isopropylidene-D-mannopyranose, which are prepared by homologation at C-1, by reaction with phenyl acetylid

A stereodivergent approach to 5a-carba-D-and L-pyranoses has been applied to the preparation of 5a-carba-a-D-gluco-, 5a-carba-a-D-galacto-, and 5a-carba-b-L-gulopyranose pentaacetates. The strategy, by which a single precursor can be transformed into three different carbasugars, features a stereosel
