A one-pot sequence of organocatalytic transformations delivers heteroarylmethylene-substituted pyrrolidines with high stereo- and enantioselectivity. A Mannich coupling of N-heteroarylalkyne aldehydes with aldimine and an original metal-free hydroamination of the resulting adducts are the key transformations of the process delivering highly functionalized molecules with high potential for synthetic applications.
