Modular multidentate phosphine ligands: Application to palladium-catalyzed allylic alkylations

Multidentate phosphines were readily obtained by reaction of chiral multidentate amines, prepared via ring opening of (S)-N-tosyl-2- isopropylaziridine with ammonia, primary, and secondary amines, with achiral phosphorus containing building blocks. The phosphines were used in palladium-catalyzed alkylation of rac-3-cyclohexenyl and cyclopentenyl carbonates. The enantioselectivity and reactivity were largely dependent on the structure of the amine core of the ligands. Up to 88% ee was observed in reactions with the six-membered substrate.

Chelating phosphines with C2 and C3 symmetry

Amide formation between ring opened aziridines and 2-(diphenylphosphino) benzoic acid provides an easy access to chelating di- and triphosphines with C2 and C3 symmetry.
