Azacyclazine derivatives were obtained from 1-benzoyl-2-phenyl-3a,6a-diazapentalene with methyl propiolate and alcohols, and from 1,3-dibenzoyl-2-phenyl-3a,6a-diazapentalene with dimethyl acetylenedicarboxylate. The former diazapentalene with diphenylcyclopropenone yielded a pyrazole. These reactions only proceeded at 10 kbar pressure and the products were identified mainly from their 1H and 13C nmr spectra.
