Abstract

The reaction of 6-substituted 3-amino-2-aryl-4(3H)-quinazolinones (1-5) with D-glucose and D-galactose in boiling methanol in the presence of acetic acid as a catalyst yielded a mixture of a- and (3-anomers of 6-substituted 2-aryl-3-[N-(D-glycopyranosyl)]-amino-4-(3H)-quinazolinones. The N-glycopyranoside derivatives 6-12 were acetylatcd with acetic anhydride/pyridine to give the corresponding acetates 13-19. Deacetylation of 13, 14, 18, 19 gave 6-substituted 2-aryl-3-[N-acetyl-N-((b-D-glycopyranosyl)]-arnino-4(3II)-quinazolinones (20-23) as sterically hindered exo- and cndoisomcrs.
