N-aryl-N′-2-thiazolylureas is reported. With cheap and recyclable nonmetal selenium instead of noble metals as the catalyst, carbon monoxide instead of virulent phosgene as the carbonylation agent, the selenium-catalyzed carbonylation reaction of 2-aminothiazole can proceed smoothly in one-pot manner with a variety of nitro aromatics in the presence of triethylamine to afford the desired N-aryl-N′-2-thiazolylureas

A number of ureidothiazole and ureidothiadiazole derivatives related to ethyl 4-[[(2-thiazolylamino)carbonyl]-amino]benzoate were prepared and evaluated against the leukemia P-388 tumor system in mice. Preliminary structure-activity relationship study revealed that, among other considerations, active compounds of this series contain either an "isothioureido" [N-C(S-)=N-] or an "isothiosemicarbazono" [N-C(S-)=N-N=] structural unit.
