A preliminary mechanistic approach to the Cu-catalyzed carboboration of alkynes using B2(pin)2 was used as a blueprint for the rational design and development of a regiocontrolled, stereoselective carboboration of internal alkynes by reaction with a β,β-disubstituted acrylate fragment to provide synthetically versatile and densely functionalized pyrrolidines. Experimental observations and computational
