Graphical Abstract

The postman always rings twice: 1-Alkynyl-3-azabicyclo[3.1.0]hexanes 2 were obtained in good to excellent yields from the stereoselective Bi(OTf)3-catalyzed dehydrative alkynylcyclopropanation of azaenynols 1, in which the propargyl alcohol motif of 1 acted as a propargyl carbene synthetic equivalent.
