An iridium-catalyzed enantioselective alkynylation of methylene CH bonds γ to the amide group is developed. The reaction proceeds through alkeneisomerization followed by regioselective hydroalkynylation. This method provides rapid access to a wide range of stereodefined alkynylated compounds in good yields and good enantioselectivities.
