A direct catalytic asymmetric vinylogous Mannich-typereaction 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-typereaction by changing the ligand. The synthetic utility of the vinylogous
The first catalytic, enantioselectivevinylogousMannichreaction of acyclic silyl dienolates is reported. A second‐generation 2,2′‐dihydroxy‐1,1′‐binaphthyl (BINOL)‐based phosphoric acid has been developed and further optimized as an enantioselective organocatalyst. Upon protonation of the imines, chiral contact ion pairs are generated in situ and attacked highly diastereoselectively by the nucleophile
