The lipase Novozym435 (0.6% w/w) was used in tandem with organocatalysts in a first vinyl/isopropenyl acetate‐mediated aldol reaction. The reaction was facilitated through the lipase‐catalyzed in situ generation of acetaldehyde/acetone. The important features of the present methodology include the mild and facile reaction conditions, regenerability of the lipase, comparatively high yields and minimal
脂肪酶Novozym435(0.6%w / w)与乙酸乙烯酯/异丙烯基乙酸酯介导的醛醇缩合反应中的有机催化剂一起使用。该反应通过脂肪酶催化的乙醛/丙酮原位生成而得以促进。本方法的重要特征包括温和且容易的反应条件,脂肪酶的可再生性,相对高的收率和最小的副产物形成。
