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

A new strategy for the protection of amines has been developed involving reaction with pyridil under the influence of N-heterocyclic carbene catalysis. The methodology is capable of distinguishing between two amines characterised by small differences in steric bulk and the resulting pyridoyl amides can be cleaved without requiring either strongly acidic or basic hydrolysis.
