Abstract

A variety of 3-substituted fused pyrimidines (4a-k) are readily obtained from the 2-amino esters (2a-k) with 2-[N-(methylthiothiocarbonyl)-amino]acetate (1). Condensed imidazo[1,2-c]pyrimidine ring system was also constructed in a one-pot process by reacting heteroaromatic 2-amino nitriles (3a-l) with 1, obtaining a number of novel tri- and tetracyclic compounds (5a-l).
