Abstract
3-Hydrazinoisoquinoline (2) was synthesized via its N-oxide derivative by removal of the N-oxide function with titanium trichloride. Acylation of the hydrazino compound (2) led to suitable starting materials (4 and 6) for cyclization to the novel, linearly fused ring system: tri-azolo[4,3-b]isoquinoline, which was more stable in the form of its perchlorate salt. The structure of the first representatives of the new ring system was proved by ir, nmr and ms spectroscopy.
