## Abstract A systematic study of the addition of various 1,2‐acyclic diones to activated acetylenic esters catalyzed by pyridine under mild conditions is described. This reaction provides a new protocol for the stereoselective synthesis of 1,2‐diaroyl maleates. The exclusive formation of the __cis
