Abstract

The Pd-catalyzed diastereoselective trifluoromethylthiolation of acrylamides was developed to allow the formation of the Z-isomer as a single product. Using a C-H bond functionalization strategy, the method was applied to a broad range of α-aryl, α-alkyl, and α,β-disubstituted acrylamides bearing the amide derived from the 8-aminoquinoline as a directing group. Mechanistic studies as well as postfunctionalization of the products were performed. This approach opens new routes to unprecedented SCF
