biological activities and physical properties. We report the first example of the iridium-catalyzed C3-selective asymmetric allylation of 7-azaindoles with racemic secondary allylic alcohols to give only branched allylation products in good to high yields with high enantioselectivity (up to >99.5% ee). Allylic alcohols and 7-azaindoles with a variety of functional groups including halogen and heteroaromatic

7-氮杂吲哚的有效合成方法。我们报告了
铱催化的
7-氮杂吲哚与外消旋仲
烯丙醇的 C3 选择性不对称烯丙基化的第一个例子,以高对映选择性(高达 >99.5% ee)仅以良好至高产率得到支化烯丙基化产物。具有多种官能团(包括卤素和杂芳族基团)的
烯丙醇和
7-氮杂吲哚与反应条件相容。此外,所获得的烯丙基化产物的转化被证明没有对映体过量的显着损失。
