convert alkenes, unsaturated aliphatic alcohols, and aryl boronic acids into secondary benzylic alcohols with high stereoselectivities (typically >95:5 er) under sequential catalysis that integrates alkene cross-metathesis, isomerization, and nucleophilic addition. Prochiral allylic alcohols can be converted to any stereoisomer of the product with high stereoselectivity (>98:2 er, >20:1 dr).
一锅法有可能迅速建立分子的复杂性,而无需分离和纯化连续的中间体。在这里,我们报告了多催化方案,该方案在顺序催化下将烯烃,不饱和脂族醇和芳基硼酸转化为具有高立体选择性(通常> 95:5 er)的仲苄醇,该催化集成了烯烃的交叉复分解,异构化和亲核加成反应。前手性烯丙醇可以高立体选择性(> 98:2 er,> 20:1 dr)转化为产品的任何立体异构体。
