Copper-catalyzed direct trifluoromethylation of propiolates: construction of trifluoromethylated coumarins.
Org Lett. 2014 Aug 15; 16(16):4240-3.OL

Abstract

A novel copper-catalyzed direct trifluoromethylation of internal alkynes was developed, obtaining a series of trifluoromethylated coumarins in good yields. The cyclization was proposed to proceed via a radical mechanism under copper-catalyzed conditions with good functional group tolerance.
