    摘要:
    在本文中,我们报道了在炔基砜存在下,通过臭氧介导和 Fe II催化的未活化烯烃的脱烯基炔基化合成烷基链炔烃。这种一锅反应采用催化 Fe II盐和L-抗坏血酸的组合,在温和的条件下进行,具有良好的效率、高立体选择性和广泛的官能团兼容性。与我们之前的 Fe II介导的 α-甲氧基氢过氧化物还原断裂相比,Fe II催化的过程是通过对多个竞争自由基(氧化还原)途径进行彻底的动力学分析而设计的。我们强调了这种脱烯基炔基化通过复杂分子(包括天然产物和药物)的多次合成后转化和后期多样化的潜力。

    摘要:
    Baeyer-Villiger单加氧酶(BVMO)介导的不对称酮的区域发散性转化可导致形成“正常”或“异常”内酯。在先前的研究中,我们能够通过将活性位点残基突变为较小的氨基酸来改变BVMO的区域选择性,从而创造了更多的空间。在这项研究中,我们证明了该方法也可用于其他BVMO /底物组合。我们调查的区域选择性2-氧代Δ 3 -4,5,5-trimethylcyclopentenylacetyl辅酶A从单加氧酶恶臭假单胞菌(OTEMO)对于顺式-二环[3.2.0]庚-2-烯-6-酮(1)和反式-二氢香芹酮(2),并且我们能够切换该酶对底物对映体之一的区域选择性。OTEMO野生型酶将(-)- 1转化为正常产物和异常产物的均等(50:50)混合物。F255A / F443V变体产生正常产品的90%,而W501V变体形成异常产品的98%。OTEMO F255A仅从(+)- 2产生正常的内酯,而野生型

    Within this study, we investigated a one-pot enzymatic redox cascade composed of different enoate reductases (5 EREDs from diverse bacterial origins) and various Baeyer-Villiger monooxygenases (4 BVMOs) with complementary regioselectivity that enabled access to six out of eight carvo-lactone stereoisomers starting from readily available natural carvones. Applicability of this two-step cascade was demonstrated

  • Crystal Structures of Cyclohexanone Monooxygenase Reveal Complex Domain Movements and a Sliding Cofactor
    作者:I. Ahmad Mirza、Brahm J. Yachnin、Shaozhao Wang、Stephan Grosse、Hélène Bergeron、Akihiro Imura、Hiroaki Iwaki、Yoshie Hasegawa、Peter C. K. Lau、Albert M. Berghuis

    Cyclohexanone monooxygenase (CHMO) is a flavoprotein that carries out the archetypical Baeyer-Villiger oxidation of a variety of cyclic ketones into lactones. Using NADPH and O-2 as cosubstrates, the enzyme inserts one atom of oxygen into the substrate in a complex catalytic mechanism that involves the formation of a flavin-peroxide and Criegee intermediate. We present here the atomic structures of CHMO from an environmental Rhodococcus strain bound with FAD and NADP(+) in two distinct states, to resolutions of 2.3 and 2.2 angstrom. The two conformations reveal domain shifts around multiple linkers and loop movements, involving conserved arginine 329 and tryptophan 492, which effect a translation of the nicotinamide resulting in a sliding cofactor. Consequently, the cofactor is ideally situated and subsequently repositioned during the catalytic cycle to first reduce the flavin and later stabilize formation of the Criegee intermediate. Concurrent movements of a loop adjacent to the active site demonstrate how this protein can effect large changes in the size and shape of the substrate binding pocket to accommodate a diverse range of substrates. Finally, the previously identified BVMO signature sequence is highlighted for its role in coordinating domain movements. Taken together, these structures provide mechanistic insights into CHMO-catalyzed Baeyer-Villiger oxidation.
