Highly enantioselective allylic alkylation catalyzed by new P,N-chelate ligands from L-valinol
Newly synthesized chiral P, N-chelate ligands gave high enantioselectivities in the alkylation of 1,3-diphenyl-2-propenyl acetate with dimethyl malonate system. High enantiomeric excess up to 98% could be obtained in a good yield.
