Regioselective preparation of 1-(bromomethyl)-5H-thiazolo[3,2- a]quinazolin-5-ones and analogous 5H-thieno[3,2-e]thiazolo[3,2-a]pyrimidin-5- ones from fused 2-(alkenylthio)pyrimidin-4-ones

A convenient procedure for the regioselective preparation of polycyclic angular thiazolo[3,2-a]pyrimidin-5-ones is reported. 2- (Alkenylthio)quinazolin-4(3H)-ones and analogues thieno[2,3-d]pyrimidines were treated with bromine in acetic acid to obtain I-
