Enantioselektive Katalyse, 96 [1]. Naphthalin-Aufbauglieder in der Synthese von optisch aktiven Zweischalenphosphinen / Naphthalene Units in the Synthesis of Optically Active Two-Layer-Phosphines

Two-layer phosphines were synthesized by reacting optically active bromonaphthyl derivatives with 1,2-bis(dichlorophosphino)ethane. The optically active bromonaphthyl ethers and amines were obtained from l-bromo-2,6-bis(bromomethyl)naphthalene and the optically active alcohol (-) borneol and the optically active amine (+)-N-methyl-3-aminomethylpinane.
