[figure: see text] Ferrocene-modified chiral pocket ligands have been studied in the palladium-catalyzed asymmetric alkylation of simple ketone enolates, in which (R,R,Sp,Sp)-1 containing two pairs of matched chiralities, central chirality and planar chirality, behaved very efficiently in this reaction and up to 95% ee value was achieved.
