One-pot synthesis of chalcone epoxides-A green chemistry strategy

Waste minimization is a very important aspect of an environmentally benign protocol. A one-pot consec-process has been developed for chalcone epoxide synthesis that allows compounds to be prepared having to isolate and purify the intermediates. The strategy utilizes consecutive Claisen Schmidt and epoxidation reactions to prepare chalcone epoxides from substituted benzaldehydes acetophenones in good yields. (C) 2014 Elsevier Ltd.
