Abstract
A copper-catalyzed coupling of imines with alkynes and acid chlorides provides an efficient and general three-component coupling method to prepare propargylamides. The coupling can also be diversified to allow the formation of N-carbamate-protected propargylamines with the use of chloroformates.
