Reactions of 4-Aminomethylene-5-oxo-2-phenyl-4,5-dihydrooxazole with Heterocumulenes The reaction of 4-aminomethylene-5-oxo-2-phenyl-4,5-dihydro-oxazole (1) with various heterocumulenes under basic conditions was examined. Depending on the nature of the heterocumulene different products were obtained. The reaction of 1 with carbon disulfide followed by alkylation yielded only 4-alkylthiomethylene-2-phenyl-5-oxo-4,5-dihydrooxazoles whereas the reaction of 1 with isothiocyanates, isocyanates and carbonyl sulfide led to the formation of 5-benzoylamino-2-thiouracils, 5-benzoylaminouracils and of 5-benzoylamino-2-methylthio-6H-1,3-oxazin-6-one, respectively.
