Abstract
Abstract Reaction of (−) 2- tert -butyl-2-methyl-1,3-benzodioxole-4-carboxylic acid with per- O -acetyl- d - and l -glucopyranosyl bromides yielded diastereomeric per- O -acetylated glycopyranosyl 2- tert -butyl-2-methyl-1,3-benzodiazole-4-carboxylates. Their 1 H-n.m.r. signals, especially the strong singlet peaks of tert -Bu and Me groups in the 1-ester portion were diagnostic for the determination of the d,l -configuration and optical purity of monosaccharides.
