title: Synthesis of enantiopure P-stereogenic diphosphacrowns using P-stereogenic secondary phosphines.
abstract: A new synthetic route to enantiopure P-stereogenic benzodiphosphacrowns using a P-stereogenic secondary bisphosphine as the key building block is reported. Syntheses of the enantiomer and P-stereogenic crowns with various ring structures, as well as deboranation of the crown compounds and subsequent reaction with a platinum complex, are described.
