  platform of engineered cytochrome P450 enzymes to carry out carbene-transfer reactions using a lactone-based carbene precursor. By simply altering the heme-ligating residue, we obtained two enzymes that catalyze olefin cyclopropanation (Ser) or S-H bond insertion (Cys). Both enzymes exhibit high catalytic efficiency and stereoselectivity, thus enabling facile access to structurally diverse spiro[2.4]lactones

  我们报告了工程细胞色素 P450 酶的生物催化平台，以使用基于内酯的卡宾前体进行卡宾转移反应。通过简单地改变血红素连接残基，我们获得了两种催化烯烃环丙烷化 (Ser) 或 SH 键插入 (Cys) 的酶。这两种酶都表现出高催化效率和立体选择性，因此可以轻松获得结构多样化的螺[2.4]内酯和α-硫代-γ-内酯。计算研究揭示了卡宾 SH 插入的机制，并解释了轴向配体如何控制反应性和选择性。这项工作扩展了血红素蛋白的催化库，并提供了有关如何调整这些酶以适应新化学反应的见解。

In this first carbon isotope effect study of an elimination reaction of an alkyl chloride, carbon-14 kinetic isotope effects have been measured in the alkoxide/bis(2-hydroxyethyl) ether-Me/sub 2/SO system for 1-(4-methylphenyl)ethyl-2-/sup 14/C chloride, k/sup ..beta../k = 1.038, 1-phenylethyl-2-/sup

  developed an efficient protocol for copper-catalyzed olefin aziridination using 5-methyl-2-pyridinesulfonamide or 2-pyridinesulfonyl azide as the nitrenoid source. The presence of a 2-pyridyl group significantly facilitates aziridination, suggesting that the reaction is driven by the favorable formation of a pyridyl-coordinated nitrenoid intermediate. Using this chelation-assisted strategy, synthetically

  我们已经开发出一种有效的方案，用于使用5-甲基-2-吡啶磺酰胺或2-吡啶磺酰基叠氮化物作为类固醇源的铜催化烯烃叠氮化。2-吡啶基的存在显着促进了叠氮基化，表明该反应是由吡啶基配位的亚硝基化合物中间体的有利形成驱动的。使用这种螯合辅助策略，即使在没有外部配体的情况下，使用一系列芳基烯烃也可以获得合成可接受的氮丙啶收率。重要的是，不需要大量过量的烯烃。X射线晶体学，ESI-MS，哈米特图分析，动力学研究和计算工作都强烈支持观察到的叠氮化是由内部配位驱动的。
