Parallel Synthesis and Screening of Polymer‐Supported Phosphorus‐Stereogenic Aminophosphane–Phosphite and –Phosphinite Ligands

Bound to Ps: An efficient, rapid, parallel solid-phase synthesis of a series of resin-bound P-stereogenic aminophosphane–phosphinite and –phosphite ligands is developed (see scheme). The ligands form active hydrogenation catalysts, displaying moderate to good enantioselectivities.
