Synthesis of polyfunctional indoles and related heterocycles mediated by cesium and potassium bases

Add time:09/25/2019    Source:sciencedirect.com

A general preparation of 2-substituted indoles starting from functionalized 2-alkynylanilines has been developed. This base mediated reaction has also been used to synthesize the heterocyclic core of the marine alkaloid hinckdentine A. Furthermore the reaction was successfully adapted to the solid phase. Benzofurans and isoindolones could also be prepared with this method.
