摘要：

The resolution of the racemate (BzlOCH(2)) (Me)C(COOH)(COOEt) (+/-)1 is the entry point for the enantioselective synthesis of the key compound 7 (MeC(CH2Cl)(CH2Br) (CH(2)OTfl)). Successive phosphination of 7 furnishes the triphosphine 10 (MeC(CH(2)PPh(2))(CH2DBP)(CH2P(3,5-Me(2)C(6)H(3))(2) in both enantiomeric forms (DBP = dibenzophospholyl). The structures of the precursors (+)8S (MeC(CH(2)PPh(2))(CH2DBP)(CH2Cl)) and (+/-)9 (MeC(CH2Br)(CH2Cl)(CH2DBP)) have been confirmed by X-ray analysis.
