    Biocatalytic asymmetric and enantioconvergent hydrolysis of trisubstituted oxiranes
    摘要:
    Asymmetric biohydrolysis of trialkyl oxiranes (+/-)-1a-3a using the epoxide hydrolase activity of whole bacterial cells proceeded in an enantioconvergent fashion and thus led to the corresponding (R)-configurated vicinal diols Ib 3b in Lip to 97% enantiomeric excess (e.e.) as the sole product. The mechanism of this enantioconvergence vas investigated by O-18-labelling experiments and it was found that both enantiomers were hydrolysed with opposite regioselectivity.

  • Oxidative Cleavage of Olefins into Carboxylic Acids with Hydrogen Peroxide by Tungstic Acid
    作者:Takahito Oguchi、Toshikazu Ura、Yasutaka Ishii、Masaya Ogawa
    DOI:10.1246/cl.1989.857
    日期:1989.5
    A facile conversion of olefins into carboxylic acids could be achieved by using aqueous hydrogen peroxide (35%-H2O2) in the presence of catalytic amounts of tungstic acid (5 wt%). The oxidation was markedly influenced by the acidity of the reaction medium, and it was found to proceed favorably under a weak acidic condition (pH 4–5).
    在催化量的钨酸 (5 wt%) 存在下,使用过氧化氢水溶液 (35%-H2O2) 可以轻松地将烯烃转化为羧酸。氧化受反应介质酸度的显着影响,并且发现在弱酸性条件下(pH 4-5)可以顺利进行。

    reduction–imine formation–intramolecular cyclization–oxidation for the general synthesis of a wide variety of biologically relevant N-polyheterocycles, such as quinoxaline- and quinoline-fused derivatives, and phenanthridines, is reported. A simple, easily available, and environmentally friendly dioxomolybdenum(VI) complex has proven to be a highly efficient and versatile catalyst for transforming a
    据报道,催化多米诺还原-亚胺形成-分子内环化-氧化用于一般合成各种生物学相关的N-多杂环,例如喹喔啉和喹啉稠合衍生物以及菲啶。一种简单、易得且环保的二氧代钼(VI)络合物已被证明是一种高效且多功能的催化剂,可用于转化涉及多种氧化还原过程的各种起始硝基芳烃。这不仅是一种可持续、步骤经济且耐空气和耐湿的方法,而且值得强调的是,序列第一步中产生的废物副产物被回收并合并到最终的目标分子中,从而改善了整体合成效率。此外,选定的吲哚喹喔啉在环己烷和甲苯中进行了光物理表征,烷基衍生物的荧光量子产率高于 0.7。
  • Regioselectivity of Rhodococcus NCIMB 11216 epoxide hydrolase: applicability of E-values for description of enantioselectivity depends on substrate structure
    作者:M. Mischitz、C. Mirtl、R. Saf、K. Faber

    an aliphatic mono- 1a and 2,2-disubstituted oxirane 3a the attack occurred exclusively at the less hindered C-atom and complete retention of configuration was retained. On the other hand, the regioselectivity was low with a 2,3-di- 4a and a trisubstituted epoxide 5a, and with a substrate bearing a benzylic oxirane atom 2a. As a consequence, the ‘Enantiomeric Ratio’ (E) can be applied to describe the
