本文描述了(邻叠氮基芳基)丙二酸酯的催化不对称施陶丁格-氮杂-维蒂希反应,允许通过氧化膦催化获得手性季羟吲哚。我们设计了一种新型 HypPhos 氧化物催化剂,可在硅烷还原剂和 Ir I基路易斯酸存在下通过 P III /P V =O 氧化还原循环实现去对称 Staudinger-aza-Wittig 反应。该反应条件温和,官能团耐受性好,底物范围广,具有优异的对映选择性。密度泛函理论表明,去对称反应中的对映选择性源于 Ir I物种和 HypPhos 催化剂的协同作用。该方法的实用性通过七种生物碱靶标的(正式)合成得到证明:(−)-胶粘蛋白 C、(−)-coerulescine、(−)-horsfiline、(+)-deoxyeseroline、(+)-esermethole、( +)-毒扁豆碱和(+)-毒扁豆碱。
