Molecular Iodine-Catalyzed Highly Stereoselective Synthesis of Sugar Acetylenes­

Abstract

d-Glycals react smoothly with alkynylsilanes in the presence of a catalytic amount of molecular iodine under mild and convenient reaction conditions to afford the corresponding alkynyl sugars in excellent yields with high α-selectivity.

Key words

molecular iodine - alkynylsilanes - C-glycosides - sugar acetylenes
