as a promising source of enzymes with unsuspected potentials as catalysts for chemical synthesis. We describe here an efficient method for one-pot indolizine synthesis that has been developed using lipase A and lipase B from Candida antarctica as biocatalysts. As showed by HPLC/MS analysis, the yield in indolizines was higher in the presence of the biocatalyst than in absence of enzyme. Lipase A, from
海洋微
生物作为一种有前途的酶来源,具有作为
化学合成催化剂的潜在潜力,引起了极大的兴趣。我们在这里描述了一种使用来自南极念珠菌的
脂肪酶 A 和
脂肪酶 B 作为
生物催化剂开发的单锅
吲哚嗪合成的有效方法。正如 HPLC/MS 分析所示,在
生物催化剂存在下,
吲哚茚的产率高于不存在酶的情况。来自南极念珠菌的
脂肪酶 A 对环加成反应显示出高催化活性和选择性。当反应在超声照射下进行时,南极念珠菌
脂肪酶催化的反应以良好的收率和很短的时间产生纯
吲哚嗪。
