Synthesis of 7,12-Dihydro-indolo[3,2-d][1]benzazepin-6-(5H)-ones and 6,11-Dihydro-thieno-[3',2':2,3]azepino[4,5-b]indol-5(4H)-one

The title compounds 4 and 6 were prepared by Fischer indole synthesis. 4a is substituted in 10-position by reaction with bromine in glacial acetic acid. A fast ring inversion is observed for the azepine ring in 4 and 6.

A novel organocatalytic approach, harnessing the unique reactivities of N-heterocyclic carbenes (NHCs), has been revealed for the construction of indoles. The NHC-catalysed atom economical synthesis of a wide range of 2-substituted indole-3-acetic acid derivatives is displayed. Strategic application of the developed method was demonstrated for a short synthesis of a cyclin-dependent kinase (CDK) inhibitor: paullone.
