Abstract
Selective pivaloylation of 2-acetamido-2-deoxy-D-glucose, its methyl alpha- and beta-glycosides, and the methyl alpha-glycoside of N-acetyl-D-muramic acid under various conditions has been studied. The structures of the products were established by 1H-n.m.r. spectroscopy and acetylation. The orders of acylation, HO-6 greater than HO-3 greater than HO-1 greater than HO-4 for 2-acetamido-2-deoxy-D-glucose and HO-6 greater than HO-3 greater than HO-4 for its methyl glycosides, were established. Methyl 2-acetamido-2-deoxy-3,6-di-O-pivaloyl-alpha- and -beta-D-glucopyranosides and 2-acetamido-2-deoxy-1,3,4,6-tetra-O-pivaloyl-D-glucopyranose were hydrolysed by rabbit serum esterases.
