  Strategies for the synthesis of N-(azacycloalkyl)bisindolylmaleimides: selective inhibitors of PKCβ

  摘要：

  N-(Azacycloalkyl)bisindolylmaleimides 1 have been identified to be selective inhibitors of PKCbeta. This manuscript will describe the synthetic approaches employed to prepare this class of compounds that resulted in development of efficient methods for preparation of N-(azacycloalkyl) indole 5, indole-3-acetamide 8 and indole-3-glyoxylate ester 4 derivatives.

• Ir-Catalyzed Reversible Acceptorless Dehydrogenation/Hydrogenation of N-Substituted and Unsubstituted Heterocycles Enabled by a Polymer-Cross-Linking Bisphosphine

  Notably, this protocol is applicable to the dehydrogenation of N-substituted indoline derivatives with various N-substituents with different electronic and steric natures. A reaction pathway involving oxidative addition of an N-adjacent C(sp3)–H bond to a bisphosphine-coordinated Ir(I) center is proposed for the dehydrogenation of N-substituted substrates.

  (phd = 1,10-phenanthroline-5,6-dione), is shown to be effective for aerobic dehydrogenation of 3° indolines to the corresponding indoles. The results show how low potential quinones may be tailored to provide a catalytic alternative to stoichiometric DDQ, due to their ability to mediate efficient substrate dehydrogenation while also being compatible with facile reoxidation by O2. The utility of the

  过渡金属/醌配合物[Ru（phd）3] 2+（phd = 1,10-菲咯啉-5,6-二酮）被证明可有效地将3°二氢吲哚有氧脱氢成相应的吲哚。结果表明，由于低电位醌具有介导有效的底物脱氢的能力，并且还与通过O2进行的容易的再氧化兼容，因此如何定制低电位的醌以提供化学计量的DDQ的催化替代物。该方法的实用性在药学上重要分子的关键中间体的合成中得到了证明。

  Enzastaurin (LY317615) is a potent and selective protein kinase C (PKC) inhibitor with an IC50 value of similar to 6 nM. [C-11] Enzastaurin (3-(1-[C-11] methyl-1H-indol-3-yl)-4-[1-[1-(2-pyridinylmethyl)-4-piperidinyl]-1H- indol-3-yl]-1H-pyrrole-2,5-dione), a new potential PET agent for imaging of PKC, was first designed and synthesized in 20-25% decay corrected radiochemical yield and 370-555 GBq/mu mol specific activity at end of bombardment (EOB). The synthetic strategy was to prepare a carbon-11-labeled maleic anhydride intermediate followed by the conversion to maleimide. (C) 2011 Elsevier Ltd. All rights reserved.
