- Synthesis of benzo[f]pyrido[1,2-a]indole-6,11-diones via the I2-promoted reactions of methyl ketones with pyridines and 1,4-naphthoquinone
-
An effective synthesis of benzo[f]pyrido[1,2-a]indole-6,11-diones has been achieved via the I2-promoted reactions of methyl ketones, pyridines and 1,4-naphthoquinone. In this reaction, either aromatic or aliphatic methyl ketones proceeded well. The advantages of this method include a broad substrate scope, metal-free reaction conditions, and high atom- and step-economy.
