  N1,N10-Ethylene-bridged high-potential flavins: synthesis, characterization, and reactivity

  摘要：

  N-1,N-10-Ethyleneisoalloxazinium chloride and its 8-Cl-, 7-CF3-, and 3-CH3-7-CF3-substituted analogs were synthesized for the purpose of exhibiting thermal reactivity with organic substrates. The new flavins were characterized spectroscopically and electrochemically, and were found to react with amines, thiols, and phenylhydrazine, the latter case exhibiting catalytic aerobic recycling. Reactions of aliphatic benzylic and cyclopropyl amines with the 7-CF3 analog were also compared to their oxidations by tris(phenanthroline)iron(III). All reactions of the flavinium salts appear to occur through heterolytic rather than homolytic mechanisms. (C) 2001 Elsevier Science Ltd. All rights reserved.

  黄素硝基烷氧化酶模拟了与NOx / TEMPO催化的相容性：醇，二醇和醚的需氧氧化。

  摘要：

  仿生黄素有机催化剂将硝基甲烷氧化为甲醛和NO x，为乙醇，二醇和醚的需氧TEMPO氧化提供了一种相对无毒，无苛刻且廉价的催化NO 2来源。醇被氧化成醛或酮，环醚被氧化成酯，末端二醇被氧化成内酯。NO x和甲醛的原位捕集表明氧化Nef过程使人联想到黄素蛋白硝基烷氧化酶的反应性，这是通过相对稳定的1,10-桥联黄素实现的。无金属的黄素/ NO x / TEMPO催化循环具有独特的相容性，尤其是与其他Nef和NO x相比生成过程，并显示出黄素催化亚砜形成的选择性。脂肪族醚通过这种方法被氧化，如（-）-氨氧化物转化为（+）-香紫苏内酯所证明的。

  novel strategy to regulate cofactor balance in vivo for whole‐cell biotransformation using a synthetic flavin analogue is reported. High efficiency, easy operation, and good applicability were observed for this system. Confocal laser scanning microscopy was employed to verify that the synthetic flavin analogue can directly permeate into Escherichia coli cells without modifying the cell membrane. This
