Synthesis and X-ray crystallographic studies of dithiepan derivatives of carbohydrates

Abstract

Nucleophilic addition of 2-lithio-2-methyl-1,3-dithian to the dialdehyde (2) gives the two diastereo-isomers (3) and (7) was transformed into a new class of carbohydrate dithiepan derivatives (11)–(13).
