An efficient and regioselective C3-alkoxymethylation of indoles has been developed with aldehydes and alcohols via three-component cascade reaction under transition-metal free conditions. This method allows for rapid access to a variety of C3-alkoxymethylaed free (N–H) indole in up to 98% yield with excellent regioselectivity. The titled products are useful building blocks in organic synthesis.
通过在无过渡金属条件下的三组分级联反应,利用醛和醇开发了吲哚的高效且区域选择性的C3-烷氧基甲基化反应。这种方法可以快速获得各种C3-烷氧基甲基化的游离(NH)吲哚,具有高达98%的产率,并具有出色的区域选择性。标题产品是有机合成中有用的组成部分。
