Stereodivergent synthesis of 5a-carba-hexopyranoses from carbohydrates via 6-exo-dig radical cyclization: Preparation of 5a-carba-β-D-manno-, α-D-allo-, β-L-talo- and α-L-gulopyranose pentaacetates from D-mannose

Four carbasugars, 5a-carba-β-D-manno-, α-D-allo-, β-L-talo- and α-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 homolo

A novel entry to 5a-carba-hexopyranoses from carbohydrates based on a 6-exo-dig radical cyclization: Synthesis of 5a-carba-β-D-mannopyranose pentaacetate

Carbohydrate-derived 2,3:4,6-diacetonides which are homologated at C-1 by reaction with phenyl acetylide undergo a 6-exo-dig radical cyclization, from a radical located at C-5, to yield highly functionalized cyclohexanes that are correlated with carba-sugars.
