Abstract: Ethyl-9-oxo-7-phenyl-4,5,7,8-tetrahydro-9H-benzo[e,f]s-inda­ceno-8-glyxolate 3 on treatment with hydrazine hydrate, semicarbazide hydrochloride and thiosemicarbazide hydrochloride yields 3-carbethoxy-6,7-dihydro-4-phenyl-lH,4H-benzo[e,f]-s-in­daceno[2,3-d]pyrazole 4,1-carbamido-3-carbethoxy-6,7-di­hydro-4-phenyl-lH,4H-benzo[e,f]-s-indaceno[2,3-d]pyrazole 5 and 3-carbethoxy-6,7-dihydro-4-phenyl-lH,4H-thiacarbamido­benzo­[e,f]-s-indaceno [2,3-d]-pyrazole 6 respectively. The structures of these compounds have been confirmed from their 1H NMR spectra.
