Abstract

A tandem SN2 alkylation/Michael addition to vinylogous carbonates based approach for the stereoselective synthesis of benzoxepines is developed. The stereoselectivity improves with an increase in the steric bulk of the substituents. The method is extended to the synthesis of benzopyranoxepines and benzoxepinopyridines with angular substituents.
