A direct catalytic asymmetric vinylogous Mannich-type reaction has been disclosed in good yield, excellent regio-, diastereo- and enantioselectivity. The key to control the regioselectivity is the combination of a bulky N-acylpyrazole and a bulky bisphosphine ligand. The catalytic system was extended to a bisvinylogous Mannich-type reaction by changing the ligand. The synthetic utility of the vinylogous products was demonstrated by several transformations.
