the development of Mo‐catalyzed asymmetric allylic alkylation reactions with 3‐alkyloxindoles as nucleophiles. The reaction is complementary to the Pd‐catalyzed reaction with regard to the scope of oxindole nucleophiles. A number of 3‐alkyloxindoles were alkylated successfully under mild conditions to give products with excellent yields and good‐to‐excellent enantioselectivities. Applications of this
我们报告了我们在开发以 3-烷基羟吲哚作为亲核试剂的 Mo 催化的不对称烯丙基烷基化反应方面所做的工作。就羟吲哚亲核试剂的范围而言,该反应与 Pd 催化反应互补。许多3-烷基羟吲哚在温和条件下成功烷基化,得到具有优异收率和良好对映选择性的产品。据报道,该方法应用于制备二氢吲哚生物碱,如 (-)-毒扁豆碱、ent- (-)-去溴氟曲明 B 和 communesin B 的吲哚啉喹啉环。
