Preparation of A1 (mixture of diastereomers)15.5 ml (23.2 mmol) of t-BuLi (1.5 M in pentane) are added dropwise to a solution of 5.98 g (23.2 mmol) of (R)-1-dimethylamino-1-ferrocenylethane in 40 ml of diethyl ether (DE) at <-10C. After stirring the mixture at the same temperature for 10 minutes, the temperature is allowed to rise to room temperature and the mixture is stirred for another 1.5 hours. This gives a solution of the compound X2 which is added via a cannula to a cooled suspension of the monochlorophosphine X1 at such a rate that the temperature does not exceed -30C. After stirring the mixture at -30C for a further 10 minutes, the temperature is allowed to rise to 0C and the mixture is stirred for another 2 hours. The reaction mixture is admixed with 20 ml of water. The organic phase is separated off, dried over sodium sulphate and the solvent is distilled off under reduced pressure on a rotary evaporator. Chromatographic purification (silica gel 60; eluent = heptane/ethyl acetate(EA)/NEthyl3(Net3) 85:10:5) gives 1 1.39 g of the desired product as a mixture of 2 diastereomers.
