  摘要：

  第二代Grubbs钌催化剂与乙烯基氧基三甲基硅烷的反应可有效生成具有N-杂环卡宾（NHC）配体的纯氢化钌络合物，并具有明确的特征。该氢化钌络合物对末端烯烃的选择性异构化和1,6-二烯的环异构化显示出高催化活性。的这些反应Ñ -allyl- Ò -vinylaniline导致新的合成方法杂环如吲哚和3-亚甲基-2,3- dihydroindoles，这对于生物活性天然产物有用的合成子。这些程序解决了面向多样性的综合中的一个重要问题。

  A facile and efficient method to produce optically pure benzofuroindolines, especially those without 3‐substituents that are susceptible to rearomatization, through [3+2] annulation of indoles with quinones is described. The suitable combination of a BOX ligand CuII hydrate complex and freshly activated molecular sieves functions to give controllably dynamic release of water, which enables the success

  accurate difunctionalization reaction undergoes a tandem process involving a radical-mediated 1,3-dipolar cycloaddtion which generated from the single-electron oxidation of N-aminopyridinium ylides, a cleavage of the N−N bond as well as an oxidation of indoline ring. The electrophilic pyridyl and nucleophilic amino groups can be installed simultaneously into a wide range of indoles under mild and metal-free

• One-Step Construction of Tetrahydro-5<i>H</i>-indolo[3,2-<i>c</i>]quinolines from Benzyl Azides and Indoles via a Cascade Reaction Sequence
  作者：Zengqiang Song、Yu-Ming Zhao、Hongbin Zhai

  DOI：10.1021/ol202656u

  日期：2011.12.16

  A novel one-step assembly of tetrahydro-5H-indolo[3,2-c]quinolines from benzyl azides and indoles via a formal [4 + 2] cycloaddition is described. A cascade reaction sequence, which involves benzyl azide-to-iminium rearrangement followed by two sequential Pictet - Spengler reactions, generates the tetracycles in moderate to excellent yields. The current method is applicable to a broad substrate scope and holds significant potential in constructing polycyclic indolines with tertiary and/or quaternary carbon centers.

  Sodium-dependent glucose co-transporter 2 (SGLT2) inhibitors are the current focus on the indication for the management of hyperglycemia in diabetes. Here, a novel series of C-linked indolylxyloside-based inhibitors of SGLT2 has been discovered. Structure-activity relationship studies revealed that substituents at the 7-position of the indole moiety and a p-cyclopropylphenyl group in the distal position were necessary for optimum inhibitory activity. The pharmacokinetic study demonstrates that the most potent compound 1i is metabolically stable with a low clearance in rats. In further efficacy study, 1i is found to significantly lower blood glucose levels of streptozotocin (STZ)-induced diabetic rats. (C) 2012 Elsevier Masson SAS. All rights reserved.
