  Biocatalytic Promiscuity of Lipase in Chemoselective Oxidation of Aryl Alcohols/Acetates: A Unique Synergism of CAL-B and [hmim]Br for the Metal-Free H₂O₂ Activation

  摘要：

  A unique synergistic combination of lipase and ionic liquid [hmim]Br is reported for metal-free H2O2 activation, which is the first example of biocatalytic promiscuity of CAL-B for chemoselective oxidation of aryl alcohols/acetates. The catalytic system exhibits excellent functional group compatibility under neutral conditions besides reusability up to ten cycles thereby making the process economically and environmentally viable.

• InCl₃/Me₃SiBr-Catalyzed Direct Coupling between Silyl Ethers and Enol Acetates
  作者：Yoshiharu Onishi、Yoshihiro Nishimoto、Makoto Yasuda、Akio Baba

  DOI：10.1021/ol200875m

  日期：2011.5.20

  A combined Lewis acid catalyst of InCl3 and Me3SiBr promoted the direct use of enol acetates in the coupling with low-reactive silyl ethers, in which functional groups including ketones and aldehydes survived. Sterically hindered silyl ethers such as ROSiEt3, ROSiPh3, ROSit-BuMe2, and ROSii-Pr3 were also applicable.

  The reactions of methoxytoluenes and methylnaphthalenes with a manganese(III) acetate–Cl− complex gave the corresponding aldehydes in 8 to 54% yields. In a similar reaction aromatic compounds having a methylene group were oxidized to the corresponding acetates and ketones. The primary and secondary benzyl alcohols gave aldehydes and ketones, respectively, in good yields. Sulfides and phosphine were

  日期：2007.9

  Copper(II) triflate doubly catalyzed the substitution of benzylic acetates by TMSN3 and the subsequent 1,3-dipolar addition with an alkyne in one pot. This procedure afforded the preparation of 1,4-disubstituted 1,2,3-triazoles in good yields starting from the easily accessible acetates without isolating an organic azide ­using a single catalyst.

  The present study describes the first-time usage of an isolated thermostable Baeyer–Villiger monooxygenase (phenylacetone monooxygenase, PAMO) in the presence of ionic liquids. The stability, activity and selectivity of PAMO as an oxidative enzyme in the presence of different ionic liquids were studied. This revealed that the addition of some specific ionic liquids, such Ammoeng™ 102 and [bmim]MeSO4, can significantly enhance the E-value in the oxidation of racemic benzylketones. Moreover, the use of ionic liquids increases the optimal substrate concentration for performing Baeyer–Villiger oxidation, thereby extending the biocatalytic repertoire of PAMO for synthetic applications.

  本研究首次报道了在离子液体存在下使用分离的耐热贝耶尔-维利格单氧合酶（苯丙酮单氧合酶，PAMO）的情况。研究了不同离子液体存在下，PAMO作为氧化酶的稳定性、活性和选择性。结果显示，添加某些特定离子液体，如Ammoeng™ 102和[bmim]MeSO4，可以显著提高消旋苯甲酮氧化反应的E值。此外，离子液体的使用提高了进行贝耶尔-维利格氧化反应的最佳底物浓度，从而扩大了PAMO在合成应用中的生物催化范围。
