Abstract

Reactions of chromium(II) aminocarboxylate complexes (ethylenediamine-tetraacetate, nitrilo-triacetate, imino-diacetate) with acetylated glycopyranosyl chlorides or bromides in liquid-liquid or solid-liquid biphasic media (such as water-diethylether, water-ethyl acetate or halosugar-water) give the corresponding glycals in 75-97% yield.
