Asymmetric Tsuji–Trost substitution in 3-acetoxy-1,3-diphenylpropene under phase-transfer conditions

P*-Chiral diamidophosphite ligand-assisted Pd-catalyzed Tsuji–Trost reaction between dimethyl malonate and prochiral 3-acetoxy-1,3-diphenylpropene in organic solvents using potassium carbonate as the base affords the substitution product in quantitative yields and with enantioselectivities up to 99% ee .
