  Mechanistic Studies of an Antibody-Catalyzed Elimination Reaction

  摘要：

  Catalytic antibody 43D4-3D12, which was generated against the substituted tertiary amine 1, catalyzes the elimination of HF from beta-fluoroketone 2. We have cloned and produced the antibody as a chimeric Fab and constructed a model of the active site-substrate complex. Mutagenesis studies of the active site indicate that Glu(H)50 acts as the general base and suggest that Tyr96(L) may also play a role in the elimination reaction. Antibody 43D4-3D12 also efficiently catalyzes the elimination of HBr from substrate 4 by an E2 mechanism, again involving selective abstraction of the proton beta-to the nitrophenyl ring by Glu(H)50. The antibody-catalyzed reaction affords predominantly the internal olefins, whereas the major product resulting from the uncatalyzed reaction is the alcohol, which arises from the competing substitution reaction. In addition, antibody 43D4-3D12 catalyzes an acetal hydrolysis reaction in which Glu(H)50 likely acts as a general acid. These studies point to the success of this particular hapten design strategy in generating an active site with a desired catalytic functional group. They also illustrate the utility of using related reactions as mechanistic probes of biological catalysis.

  β-unsaturated ketones. Afterward, these compounds react with different commercially available ene-reductases to afford the corresponding saturated ketones. Remarkably, in the case of trisubstituted alkenes, the bioreduction reaction occurred with high stereoselectivity. Overall, a bienzymatic one-pot two-step sequential strategy has been described with respect to the synthesis of saturated ketones starting

  在温和的反应条件下，在水性介质中设计催化氧化方法，并使用分子氧作为最终电子受体，是传统氧化转化的合适替代方法。如果在同一分子内存在其他可氧化的官能团（如烯丙醇的情况），则这些方法尤为重要。本文我们应用漆酶组成的简单化学酶促系统从云芝和2,2,6,6-四甲基自由基（TEMPO），以氧化一系列外消旋烯丙基的秒-醇转化为相应的α，β-不饱和酮。然后，这些化合物与不同的市售烯还原酶反应，得到相应的饱和酮。显着地，在三取代的烯烃的情况下，生物还原反应以高的立体选择性发生。总的来说，关于从外消旋烯丙基醇开始的饱和酮的合成，已经描述了双酶一锅两步顺序策略，因此类似于先前在文献中报道的这些衍生物的金属催化的氧化还原异构化。

The presence of tin/tin chloride mixture in the reaction of the aryl diazonium salts with methyl vinyl ketone produced Michael products along with β-aryl methyl ketones. The predicted α-aryl methyl ketones from the reaction of isopropenyl acetate with the diazotized anilines were obtained using iron or tin/tin
