Ac. Gillard et al., PYRROLO[2,1-C][1,4]BENZODIAZEPINES - SYNTHESIS OF NEW CYCLIC AMIDINESAND FUSED[A]TRIAZOLO, TETRAZOLO AND OXADIAZOLO DERIVATIVES, Journal of heterocyclic chemistry, 34(2), 1997, pp. 445-451
We report the practical synthesis of new cyclic amidines from thiolact
ams and the preparation of fused[a]triazolo, tetrazolo and oxadiazolo
derivatives via hydrazidines and oximes, in the pyrrolo[2,1-c][1,4]ben
zodiazepine series.
