  双金属自由基氧化还原继电器催化环氧化物异构化为烯丙醇

  摘要：

  有机自由基通常是具有异常高反应性的短寿命中间体。从战略上讲，实现由有机自由基介导的合成有用的转化需要有效的引发和选择性终止事件。在这里，我们报告了一种新的催化策略，即双金属自由基氧化还原继电器，用于环氧化物向烯丙醇的区域和立体选择性重排。这种方法利用了 Ti 和 Co 配合物的丰富氧化还原化学，并将还原性环氧化物开环（引发）与氢原子转移（终止）相结合。至关重要的是，在影响关键的成键和断裂事件时，Ti 和 Co 催化剂彼此进行质子转移/电子转移以实现周转，从而构成真正协同的双催化系统。

  Glycosidases are very important enzymes involved in a variety of biochemical processes with a special importance to biotechnology, food industry, and pharmacology. Novel structurally simple inhibitors derived from cyclohexane-1,2-dicarboxylic acids were synthesized and tested against several fungal glycosidases from Aspergillus oryzae and Penicillium canescens. The presence of at least two carboxylic groups and one hydroxy group was essential for efficient inhibition. Significant selective inhibition was observed for alpha- and beta-glucosidases, the magnitude of which depended on the configuration of substituents; inhibition increased for p-glucosidase by lengthening the alkoxy group of the inhibitor.

• A diastereoselective P450-catalyzed epoxidation reaction: anti versus syn reactivity
  作者：Adriana Ilie、Richard Lonsdale、Rubén Agudo、Manfred T. Reetz

  日期：2015.6

  The achiral cyclohexene derivative dimethyl cis-1,2,3,6-tetrahydrophthalate has been subjected to oxidation catalyzed by cytochrome P450 monooxygenase P450-BM3, leading to diastereoselective epoxidation rather than oxidative hydroxylation. This reaction occurs with 94% diastereoselectivity in favor of the anti-epoxide, in contrast to m-CPBA which delivers unselectively a 70:30 mixture of anti/syn diastereomers. The experimental results are nicely explained on a molecular level by docking experiments and molecular dynamics computations. (C) 2015 Elsevier Ltd. All rights reserved.
