General and Stereoselective Method for the Synthesis of Sterically Congested and Structurally Diverse P‑Stereogenic Secondary Phosphine Oxides

A general and efficient method for the synthesis of bulky and structurally diverse P-stereogenic chiral secondary phosphine oxides (SPOs) by using readily available chiral amino alcohol templates is described. These chiral SPOs could be used as chiral building blocks for the synthesis of difficult-to-access bulky P-stereogenic phosphine compounds or ligands for organic catalysis.
