Reactions with Pyrrolidine-2,4-diones, II: New Approaches to the Synthesis of Substituted 5,6-Dihydropyrrolotriazol-4(2H,4H)ones

Approaches leading to 5,6-dihydro-5,6-diphenyl-2-substituted-pyrrolotriazol-4(2H,4H)-ones (10) are described.The first approach consists of cyclodehydrating 3(or 4)-hydroxyimino-1,5-diphenyl-4(or 3)-(4-substituted phenylhydrazono)pyrrolidin-
