| مستخلص: |
New bis(diamidophosphite) ligand with stereogenic phosphorus atoms in the 1,3,2-diaza-phospholidine rings was synthesized based on (1R,2R)-[N, N′-bis(3-hydroxybenzylidene)]-1,2-diaminocyclohexane. This ligand provided up to 73% ee in Pd-catalyzed asymmetric allylic alkylation of (E)-1,3-diphenylallyl acetate with dimethyl malonate and up to 80% ee in its amination with pyrrolidine, with the starting substrate conversion being quantitative.
