enantioselective desymmetrization reaction of bisphenol compounds with achiral Morita–Baylis–Hillman carbonate agents was developed. Through the asymmetric allylic alkylation strategy, a broad range of optically active P-stereogenic phosphine oxides were generated with excellent to good yields (up to 99%) and high enantioselectivities (up to 98.5 : 1.5 e.r.). The reaction was further investigated by the linear

碳酸盐试剂的高度对映选择性脱对称反应得以开发。通过不对称的烯丙基烷基化策略,可以生成多种旋光性P-立体异构的氧化膦,具有优异至良好的收率(高达99%)和高对映选择性(高达98.5:1.5 er)。通过线性自由能关系(LFER)分析进一步研究了该反应。提出了一种可能的过渡态,并通过理论计算进一步验证。
