Synthesis of a New Optically Active Triphosphine with a Neopentane Backbone

Horst Heidel, Gottfried Huttner and Laszlo Zsolnai


The resolution of the racemate (BzlOCH2)(Me)C (COOH)(COOEt) (±)1 is the entry point for the enantioselective synthesis of the key compound 7 (MeC(CH2Cl)(CH2Br)(CH2OTfl)). Successive phosphination of 7 furnishes the triphosphine 10 (MeC(CH2PPh2)(CH2DBP)(CH2P(3,5-Me2C6H3)2) in both enantiomeric forms (DBP = dibenzophospholyl). The structures of the precursors (+)8S(MeC(CH2PPh2)(CH2DBP)(CH2Cl)) and (±)9 (MeC(CH2Br)(CH2Cl)(CH2DBP)) have been confirmed by X-ray analysis.
