Facile formation of cyclic aminals through a Brønsted acid-promoted redox process.

Chen Zhang1, Sandip Murarka, Daniel Seidel.   

Abstract

Cyclic aminals were prepared through a Brønsted acid-promoted reaction. This redox neutral process involves iminium ion formation, 1,5 H-transfer, followed by ring closure.
