Abstract

An efficient method for the synthesis of 2,6-multisubstituted morpholines via an electrochemical intramolecular etherification has been developed. The method, which is operationally simple and easy to scale up, provides various substituted morpholine derivatives in high yields. The utility of this method is showcased by the synthesis of 2,2,6,6-tetrasubstituted morpholines, which are difficult to synthesize efficiently using previously reported strategies.
