A dual platinum‐ and pyrrolidine‐catalyzed direct allylic alkylation of allylic alcohols with various active methylene compounds to produce products with high monoallylation selectivity was developed. The use of pyrrolidine and acetic acid was essential, not only for preventing undesirable side reactions, but also for obtaining high monoallylation selectivity.
开发了双铂和吡咯烷催化的烯丙基醇与各种活性亚甲基化合物的直接烯丙基烷基化反应,以生产具有高单烯丙基化选择性的产品。吡咯烷和乙酸的使用是必不可少的,不仅用于防止不良的副反应,而且用于获得高的单烯丙基化选择性。
