Ring Transformation of Fused Pyridazines. VI. Construction of 3-(2-Pyridyl)indole Skeleton by Means of N-N Bond Cleavage Reaction of Fused Pyridazines with Ynamines
We established a new N-N bond cleavage reaction of pyridazino[4,5-b]indoles with ynamines to form 3-(2-pyridyl)indoles. The latter are easily converted to 3-(2-piperidyl)indoles, which are key intermediates for the synthesis of indole alkaloids.
