The substituted thioureas 3s -4 prepared from 3-phenyl-2propenoyl isothiocyanate (1) and aromatic or heteroaromatic ' amines 2a-II, cyclize in the presence of sodium ethoxide to give the perhydropyrimidine derivatives 51-c
In conjunction with a project towards development of simple new approaches for the synthesis of heterocycles, the utility of the reaction of 3-phenyl-2-propenoyl isothiocyanate (1) with aromatic and heteroaromatic amines for the synthesis of polyfunctional heterocycles has been investigated 2,3).
