Abstract
8-Oxo-8H-4,5,6,7-tetrahydropyrazolo[5,4-c]azepine and a mixture of 2-phenyl-8-oxo-8H-4,5,6,7-tetrahydro [3,4-c]azepine and 2,3-dioxo-4-formylhexahydroazepine 4-phenylhydrazone were obtained in the reactions of 2,3-dioxo-4-(N,N-dimethylaminomethylene)-hexahydroazepine with hydrazine and phenylhydrazine, respectively. Cyclization of 2,3-dioxo-4-formylhexahydroazepine 4-phenylhydrazone gave 1-phenyl-8-oxo-8H-4,5,6,7-tetrahydropyrazolo [5,4-c]azepine. The reaction of 2,3-dioxo-4-(N,N-dimethylaminomethylene)hexahydroazepine with semicarbazide and thiosemicarbazide gives 2,3-dioxo-4-formylhexahydroazepine 4-semicarbazone and 4-thiosemicarbazone.
