摘要
在二氯化镍和噻唑盐类氮杂环卡宾有机催化剂共存下,以苯甲醛和醋酸肉桂酯为起始原料,通过一锅内的安息香缩合反应和α-羟基酮型烯丙基亲核取代串联反应,在K2CO3作碱、THF为溶剂的温和条件下,合成了烯丙基化的α-羟基酮化合物,收率达78%。
With the presence of nickel( Ⅱ ) chloride as metal complex catalyst and N-heterocyclic carbene as organic catalyst effective one pot synthesis of allylated a-hydroxy carbonyl compound in 78% yield was developed using benzaldehyde and cinnamyl acetate as precursors in potassium carbonate THF solution. The involved reactions during the continuous reaction are benzoin condensation and allylic nucleophilic substitution.
