Diamidophosphite and phosphite ligands with (S)-2-(anilinomethyl)pyrrolidine or (Sa)-BINOL backbone and porphyrin cores were obtained. The use of these ligands provides up to 92 % ee (enantiomeric excess) in Pd-catalyzed asymmetric alkylation of (E)-1,3-diphenylallyl acetate with dimethyl malonate, up to 82 % ee in its sulfonylation with sodium p-toluene sulfinate and up to 76 % ee in its amination with pyrrolidine. Also, up to 90 % ee was achieved in Pd-catalyzed allylic alkylation of cinnamyl acetate with ethyl 2-oxocyclohexane-1-carboxylate. The influence of the structural moieties such as the nature of phosphorus-containing ring or porphyrin exocyclic substituent on the catalytic activity and enantioselectivity are discussed.
