Trivalent dialkylaminopyridine-catalyzed site-selective mono-O-acylation of partially-protected pyranosides

Abstract

The work demonstrates trivalent tris-(3-N-methyl-N-pyridyl propyl)amine (1) catalyzing the site-selective mono-O-acylations of glycopyranosides. Varied acid anhydrides are used for the acylations of monosaccharides, mediated by the catalyst 1, at a...
