Abstract

The condensation of 6, 6-dimethyl-4, 5-dioro-l -phenyl-4, 5, 6, 7-tetrahydroindazole with the 1, 3-cyclanediones 1,3-indanedione and barbituric acid in the presence of piperidine acetate gave 4-(1,3-indanedion-2-ylidene)-and 4-(2, 4, 6-trioxo-4, 5-dihydro-5 pyrimidylidene)-5-oxo-l -phenyl-4, 5, 6, 7-tetrahydroindazoles respectively. With hydrazine hydrate the former readily gave 4, 4-dimethyl-12-oxo-3-phenyl-4, 5-dihydro-10H-indeno(3, 2-c]pyrazolo(4, 5-flcinnoline.
