Eight new chiral oxazolinylpyridines were prepared and assessed in the enantioselective palladium-catalyzed allylic substitution of 1,3-diphenylprop-2-enyl acetate with dimethyl malonate. Catalytic activity and enantioselectivity were found to be highly dependent upon the steric requirement of the substituent on the pyridine ring: enantioselectivity up to 92% has been obtained.
