2-Hydrazinocyclohepta[b]pyrrole reacted with dimethyl acetylenedicarboxylate (DMAD) to give the hydrazones (2a), the pyrimidinone-fused cyclohepta[b]pyrrole (3), 1,2,4-triazinone-fused cyclohepta[b]pyrroles, and the 1,2-dihydro-3H-pyrazol-3-one derivative. Thermolysis of 2a gave 3 and tetramethyl pyrrole-2,3,4,5-tetracarboxylate. The reaction of ethyl cyclohepta[b]pyrrole-3-carboxylate with DMAD at room temperature gave the hydrazone and the spiropyrazoline derivative.
