amenable for late-stage functionalization of natural compounds and biologically relevant motifs, allowing a straightforward synthesis of a large library of CF3-containing enamides, the high-value pharmacophores, in a single step from readily accessible amides, Langlois’ reagent, and alkynes. The current methodology can also be successfully extended to difluoromethylamidation of alkynes. Additionally
