with diverse biological activities. A series of chiral ϵ-benzosultams bearing phosphorus functionalities was synthesized by catalytic asymmetric hydrophosphonylation in the presence of a bifunctional phosphonium salt catalyst. The desired hydrophosphonylation products were obtained in good yields with high enantioselectivities, and scale-up reactions and further derivations were successfully accomplished

生物活性的潜在候选药物。在双功能
鏻盐催化剂存在下,通过催化不对称氢膦酰化反应合成了一系列带有
磷官能团的手性 ϵ-benzosultams。以良好的收率和高对映选择性获得了所需的氢膦酰化产物,并且成功地完成了放大反应和进一步的衍生。还进行了一些对照实验以阐明这种
化学转化的合理反应机制。
