Complexing and Catalytic Properties of Easily Available Chiral Iminophosphite
on Biphenyl-2,2'-diol. — A new chiral iminophosphite ligand based on biphe02- 050 Based
nyldiol is presented, which is successfully applied in the palladium-catalyzed asymmetric alkylation of allylic acetate (I) and carbonate (VI). Enantioselectivities of up to
88% e.e. are achieved. Interestingly, for the sulfonylation of acetate (I) better results
are achieved with a rhodium complex. — (TSAREV*, V. N.; KABRO, A. A.;
