An unprecedented substrate-directed, iridium-catalyzed enantioselective hydroalkynylations of trisubstituted alkenes to form acyclic all-carbon quaternary stereocenter β to a nitrogen atom was reported. The hydroalkynylation of enamide occurred with unconventional selectivity, favoring the more hindered reaction site. Homopropargyl amides with β-stereocenters were prepared in high regio- and enantioselectivities. Combined exptl. and computational studies revealed the origin of the regio- and enantioselectivities.
