Because the mechanism of allylic alkylation involves the bond breaking or making events occurring outside the coordination sphere of palladium, an approach for asymmetric induction envisions chiral pockets to influence the events.A strategy to synthesize such chiral receptors is developed.A modular ligand design depends upon the employment of trans-1,2-diaminocyclohexane as a chiral scaffold which induces conformational chirality of an attached 2-(diarylphosphino)benzoic acid moiety.The synthesis of methylbenzoate via a novel cross coupling reaction provides a convenient template for attachment of a variety of substituents, also using cross-coupling reactions. - Keywords: chiral ligand; cross-coupling; phosphine
