Highly regio-, diastereo-, and enantioselective Pd-catalyzed allylic alkylation of acyclic ketone enolates with monosubstituted allyl substrates

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%.
