Abstract
Chiral P*,S-diamidophosphites with a 1,3,2-diazaphospholidine core and exocyclic 1,2-hydroxyl-thioether fragments were prepared. These asymmetric inducers provided up to 86% ee in the Pd-catalyzed allylic substitution of (E)-1,3-diphenylallyl acetate with dimethyl malonate and pyrrolidine, and up to 76% in the Pd-mediated allylic alkylation of cinnamyl acetate with ethyl 2-oxocyclohexane-1-carboxylate.
