An unexpected reductive transformation of 1-substituted 5-hydroxy-4,5-diphenyl-1H-imidazol-2(5H)-ones (imidazolones) and their cyclic analogs to give 1-substituted 4,5-diphenyl-1H-imidazol-2(5H)-ones (imidazolinones) upon reaction with thiourea and hydroc

A general and highly selective method for the synthesis of 4-substituted 3a,6a-diphenyltetrahydro-2H-imidazo[4,5-d][1,3]thiazole-2,5(3H)-diones has been developed through a new reaction of 1-substituted 5-hydroxy-4,5-diphenyl-1H-imidazol-2(5H)-ones with p

4,5-Diphenyl-4-oxazolin-2-one and -2-thione undegro recyclization to 1-substituted 4,5-diphenyl-4-imidazolin-2-ones and -2-thiones, respectively, under the influence of primary amines.The action of hydrazine hydrate on the oxazolone leads to 5,6-diphenyl-1,2,3,4,-tetrahydro-1,2,4-triazin-3-one.The corresponding ureas were isolated from the reaction mixtures in a number of cases.
