New phosphite and amidophosphite inductors of chirality were obtained based on ((4R,5R)-2,2-dimethyl-1,3-dioxolane-4,5-diyl)bis(diphenylmethanol) ((R,R)-TADDOL) containing arylamino groups in the exocyclic substituents.

New phosphite and amidophosphite inductors of chirality were obtained based on ((4R,5R)-2,2-dimethyl-1,3-dioxolane-4,5-diyl)bis(diphenylmethanol) ((R,R)-TADDOL) containing arylamino groups in the exocyclic substituents. Their use in the palladium-catalyzed enantioselective alkylation of (E)-1,3-diphenylallyl acetate with dimethyl malonate gave the ee value up to 98%.
