A general and benign iron‐catalyzedα‐alkylation reaction of ketones with primary alcohols has been developed. The key to success of the reaction is the use of a Knölker‐type complex as catalyst (2 mol %) in the presence of Cs2CO3 as base (10 mol %) under hydrogen‐borrowing conditions. Using 2‐aminobenzyl alcohol as alkylation reagent allows for the “green” synthesis of quinoline derivatives.
酮与伯醇的一般性和良性铁催化的α-烷基化反应已得到开发。该反应成功的关键是在氢借入条件下,在存在Cs 2 CO 3作为碱(10摩尔%)的情况下,使用Knölker型络合物作为催化剂(2摩尔%)。使用2-氨基苄醇作为烷基化试剂可实现喹啉衍生物的“绿色”合成。
