Lithium N-benzyl-α-methylbenzylamide adds to prochiral vinyl phosphine oxides in the presence of trimethylsilyl chloride to provide, after protodesilylation, β-amino phosphine oxides as single diastereoisomers. A mechanism which explains the rôle of trimethylsilyl chloride is proposed.
N-苄基-α-甲基苄基氨基化锂在三甲基甲硅烷基氯的存在下加到前手性乙烯基膦氧化物中,以在原去甲硅烷基化之后提供β-氨基膦氧化物作为单一的非对映异构体。提出了解释三甲基甲硅烷基氯的作用机理的机理。
