A Dieckmann/Ring Expansion Approach to Tetrahydropyrido- and Tetrahydroazepino-(1,2-a)indoles.

Abstract A general Dieckmann/ring expansion approach to fused [1,2-a]indole systems is reported. This approach has allowed the synthesis of a large variety of substituted systems required for the preparation of a series of potent and selective inhibitors of Protein Kinase C.
