    摘要:
    在碘化钠存在下,氯化铈 (III) 七水合物以非凡的效率催化 1,3-二羰基化合物与 α,β-不饱和酮和 α,β-不饱和醛的迈克尔加成反应。非常温和的条件允许高化学选择性,如不存在典型副反应所示,这可以在常规碱催化过程中观察到。更有趣的是,当至少一种原料在室温下为液体时,反应也可以在没有溶剂的情况下进行。CeCl3·7 H2O/NaI 催化剂体系可以很容易地从反应混合物中分离出来,并且可以重复使用而不会明显损失活性。讨论了本程序的优点,它使用了便宜且“友好”的试剂,而不是以前报道的试剂。

  • Fast Carbon−Carbon Bond Formation by a Promiscuous Lipase
    作者:Maria Svedendahl、Karl Hult、Per Berglund
    DOI:10.1021/ja056660r
    日期:2005.12.1
    Lipase B from Candida antarctica was redesigned to catalyze the promiscuous reaction of carbon-carbon bond formation. Mutation of the catalytic serine to alanine afforded a mutant that catalyzed Michael additions of 1,3-dicarbonyls to alpha,beta-unsaturated carbonyl compounds at high specific rates, such as 4000 s-1. The enzyme-catalyzed Michael addition reaction followed saturation kinetics and showed
    来自南极念珠菌的脂肪酶 B 被重新设计以催化碳-碳键形成的混杂反应。催化丝氨酸突变为丙酸提供了一种突变体,该突变体以高比速率(例如 4000 s-1)催化 1,3-二羰基化合物与 α,β-不饱和羰基化合物的迈克尔加成。酶催化的迈克尔加成反应遵循饱和动力学并显示底物抑制。设计的酶显示出高速率增强,催化效率高于 108,与对具有天然底物的酶观察到的平相同。
