Because of its broad spectrum of biological activities, a novel series of thienopyrimidines and fused thienopyrimidines have been synthesized by reacting the enaminonitrile 1 with different reagents. Thus, reaction of 1 with urea, thiourea, formic acid and/or formamide afforded pyrimidine derivatives 2, 3, 4, and 5, respectively. Compound 4 reacted with POCl3/PCl5 giving the chloro-derivative 7 which
