    Comparison of substituted 2-nitrophenol degradation by enzyme extracts and intact cells
    摘要:
    The first catabolic pathway enzyme, nitrophenol oxygenase, transforms o-nitrophenol (ONP) to catechol. Thirteen of 16 substituted nitrophenols tested were actively transformed by both enzyme preparations and intact cells yielding a wide range of K(m) (K(s)) and V(max). Individual chemicals in binary mixtures demonstrated competitive inhibition. Chemical and physical characteristics (electron withdrawal, size, and position of substitution on the 2-nitrophenol ring) affected degradation kinetics. The strongest correlations were between K(m) or V(max) values and electron withdrawal, though there was also evidence for effects relating to position and size of substitution on the aromatic ring. Kinetic parameters determined for enzyme preparations did not correlate to those determined for intact cells. Though enzyme reactivity ultimately determined whether a given chemical would be transformed, the transformation by intact cells was apparently affected by factors other than those directly impacting the initial catabolic enzyme.

  • Efficient <i>ortho</i>-Oxidation of Phenols with Diacyl Peroxides
    作者:Masahiro Tada、Risa Ishiguro、Ryohei Izumi
    DOI:10.1248/cpb.56.239
    日期:——
    A stable symmetric diacyl peroxide, m-chlorobenzoyl peroxide (mCBPO), and an asymmetric diacyl peroxide, chloroacetyl m-chlorobenzoyl peroxide (CAMCBPO), were synthesized from m-chloroperbenzoic acid. Both peroxides oxidized phenols selectively at the ortho position predoninantly. CAMCBPO gave para-oxidized compounds as minor products from some phenols. The improvement of the yield of ortho-oxidation of phenols with mCBPO was also reported.
    从间氯过苯甲酸出发,合成了稳定的对称二酰基过氧化物间氯苯甲酰过氧化物(mCBPO)和非对称二酰基过氧化物氯乙酰基间氯苯甲酰过氧化物(CAMCBPO)。这两种过氧化物主要选择性地在苯酚的邻位进行氧化。从某些苯酚出发,CAMCBPO得到了少量对位氧化产物。还报道了使用mCBPO提高苯酚邻位氧化产率的方法。
  • Synthesis of α-oxygenated ketones and substituted catechols via the rearrangement of N-enoxy- and N-aryloxyphthalimides
    作者:Michelle A. Kroc、Aditi Patil、Anthony Carlos、Josiah Ballantine、Stephanie Aguilar、Dong-Liang Mo、Heng-Yen Wang、Daniel S. Mueller、Donald J. Wink、Laura L. Anderson

    日期:2017.7
    synthesis of α-oxygenated carbonyl compounds and catechols is the treatment of a carbonyl compound or a phenol with an electrophilic oxygen source. As an alternative approach to these important structures, formal [3,3]-rearrangements of N-enoxyphthalimides, N-enoxyisoindolinones, and N-aryloxyphthalimides have been explored. When used in combination with an initial Chan-Lam coupling, these transformations
    合成α-氧化羰基化合物和邻苯二酚的常用方法是用亲电子氧源处理羰基化合物或苯酚。作为这些重要结构的替代方法,已经研究了N-烯氧基邻苯二甲酰亚胺,N-烯氧基异吲哚满酮和N-芳氧基邻苯二甲酰亚胺的形式[3,3]重排。当与初始Chan-Lam偶联结合使用时,这些转化有助于烯基硼酸的双氧合以合成α-加氧的酮和芳基硼酸的双氧合以合成儿茶酚。N-烯氧基异吲哚啉酮的重排也已显示为非对映选择性的。
  • A Catalyst-Controlled Aerobic Coupling of<i>ortho</i>-Quinones and Phenols Applied to the Synthesis of Aryl Ethers
    作者:Zheng Huang、Jean-Philip Lumb
    DOI:10.1002/anie.201606359
    日期:2016.9.12
    ortho‐Quinones are underutilized six‐carbon‐atom building blocks. We herein describe an approach for controlling their reactivity with copper that gives rise to a catalytic aerobic cross‐coupling with phenols. The resulting aryl ethers are generated in high yield across a broad substrate scope under mild conditions. This method represents a unique example where the covalent modification of an ortho‐quinone

  • Selective<i>Ortho</i>-Hydroxylation-Defluorination of 2-Fluorophenolates with a Bis(μ-oxo)dicopper(III) Species
    作者:Joan Serrano-Plana、Isaac Garcia-Bosch、Ryosuke Miyake、Miquel Costas、Anna Company
    DOI:10.1002/anie.201405060
    日期:2014.9.1
    The bis(μoxo)dicopper(III) species [CuIII2(μ‐O)2(m‐XYLMeAN)]2+ (1) promotes the electrophilic ortho‐hydroxylation–defluorination of 2‐fluorophenolates to give the corresponding catechols, a reaction that is not accomplishable with a (η2:η2‐O2)dicopper(II) complex. Isotopic labeling studies show that the incoming oxygen atom originates from the bis(μoxo) unit. Ortho‐hydroxylation–defluorination occurs

In the next step, amino acids have been applied as nontoxic and cheap alternatives for amines. The obtained products were similar with the regular amines case. This is the first report about the application of amino acids as alternatives for primary amines
