Intramolecular acylation of γ-benzoyloxy phosphine oxides with LDA in the presence of Me3SiCl give silyl ethers with high steroselectivity: treatment of these silyl ethers with t-BuOK gives optically active di- and trisubstituted cyclopropyl ketones in good yield.
在Me 3 SiCl存在下,用LDA对γ-苯甲酰氧基氧化膦进行分子内酰化,可得到具有高立体选择性的甲硅烷基醚:用t-BuOK处理这些甲硅烷基醚可得到具有良好光学收率的二和三取代的环丙基酮。
