Cu(Ⅱ)-mediated b-C-H alkynylation of acrylamides with terminal alkynes is described by employing amide-oxazoline bidentate auxiliary, forming the conjugated 1,3-enynes. This protocol is characterized by its mild conditions, broad substarate scope and excellent regio- and stereo-selectivity.

Key words: b-C-H alkynylation, copper, 1,3-enynes, stereo-selectivity
