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