Sequential Aldol/Michael Addition Reaction in Ionic Liquid Catalyzed by Morpholine: A Convenient Synthesis of 1,3,5‐Triaryl‐1,5‐pentanedione

Abstract

A series of 1,3,5‐triaryl‐1,5‐pentanediones was obtained via a sequential aldol condensation and Michael addition reaction in ionic liquid catalyzed by morpholine, as a one‐pot reaction. The significance of our findings relates to reducing the use of organic solvents, potentially toxic and hazardous materials, as well as its simplicity, good yields, mild conditions, and lower costs.
