摘要

A series of phenylallyl-substituted unsymmetrical ureas were synthesized in a one-pot procedure by reactions of cinnamoyl isocyanate, which was prepared from cinnamoyl azide by Curtius rearrangement, with various aromatic amines, 2-amino-5-aryl-1, 3, 4-thiadiazoles and 2-amino-5-aryloxymethylene-1, 3, 4-thiadiazoles under microwave irradiation. Compared to conventional methods, this synthesis has the advantages of mild reaction ...
