Abstract

(2',3'-O-Isopropylidene-5'-uridyl) 4-(2,3,4,6-tetra-O-acetyl-beta-d-glycopyranosyl)allophanates were obtained in the reactions of 2',3'-O-isopropylidene-uridine and O-peracetylated beta-d-gluco-, galacto- and xylopyranosylamines, and OCNCOCl. 2,3,4,6-Tetra-O-acetyl-beta-d-glucopyranosyl isocyanate and N-(2',3'-O-isopropylidene-5'-uridyl)urea gave 1-(2,3,4,6-tetra-O-acetyl-beta-d-glucopyranosyl)-5-(2',3'-O-isopropylidene-5'-uridyl)biuret. Deprotection of the beta-d-gluco configured allophanate and biuret was carried out by standard methods.Copyright 2009 Elsevier Ltd. All rights reserved.
