| 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. |
