摘要：

A generalizable procedure for production of pure enantiomeric chelating phosphanes is based on the surprisingly facile resolution of the corresponding phosphane oxides—(±)‐norphosO in this case—with L‐()‐dibenzoyltartaric acid. (+)‐ and ()‐norphosO (optically pure after two separation steps) can reduced by SiHCl3 to (+)‐ and () norphos, respectively, which from valuable catalysts for asymmetric hydrogenation with Rh compounds.
