Diamidophosphites from β-hydroxyamides: readily assembled ligands for Pd-catalyzed asymmetric allylic substitution.

Two groups of modular chiral diamidophosphite ligands were easily synthesised from accessible N-Boc-amino alcohols and pseudodipeptides. The reaction of these compounds with [Pd(allyl)Cl] in the presence of AgBF yielded complexes [Pd(allyl)(L)]BF. In addition, metallochelates [Pd(allyl)(L)]BF with (S)-methioninol-based P,S-bidentate ligands were prepared.
