Highly Regio-, Diastereo-, and Enantioselective Pd-Catalyzed Allylic Alkylation of Acyclic Ketone Enolates with Monosubstituted Allyl Substrates

Abstract

Pd-catalyzed asymmetric allylic alkylation reactions of acyclic ketones with monosubstituted allyl substrates using 1,1‘-P,N-ferrocene with H as substituent on the oxazoline ring as ligand gave products having two chiral centers with high yields and with high regio-, diastereo-, and enantioselectivities, with the ratio of branched and linear products being 98:2, anti:syn ratio for branched products being 7−21:1, and ee for the anti-products being 92−99%.
