  摘要：

  NHC-promoted O- to C-carboxyl transfer of 3-allyl indolyl phenyl carbonates generates 3-allyl-3-phenoxycarbonyl-oxindoles with good catalytic efficiency, which are readily converted into (+/-)-N-benzylcoerulescine and (+/-)-horsfiline. (C) 2010 Elsevier Ltd. All rights reserved.

  通过 RCM、氢化和酸催化扩环有效合成环庚[b]吲哚和环庚[b]吲哚-吲哚啉缀合物：仿生方法

  摘要：

  环庚[b]吲哚的有效催化组装是通过顺序转化实现的：闭环复分解、催化氢化和酸催化扩环。羟吲哚的闭环复分解（RCM）和氢化产生螺环己烷-3-羟吲哚。随后由路易斯或布朗斯台德酸催化的自发扩环芳构化序列产生环庚[ b ]吲哚或环庚[ b ]吲哚-二氢吲哚缀合物。

• Kinetic Resolution of Tertiary Alcohols: Highly Enantioselective Access to 3-Hydroxy-3-Substituted Oxindoles
  作者：Shenci Lu、Si Bei Poh、Woon-Yew Siau、Yu Zhao

  DOI：10.1002/anie.201209043

  日期：2013.2.4

  Enantioselective: The first highly enantioselective kinetic resolution of 3‐hydroxy‐3‐substituted oxindoles has been developed through oxidative esterification catalyzed by a N‐heterocyclic carbene (see picture). This method uses a simple procedure and provides 3‐hydroxy‐oxindoles with various substituents at the 3‐position in excellent enantiopurity. S=selectivity.

  The use of ytterbium(II) reagent as both nucleophilic reagent and single-electron transfer reagent in the reaction of isatin derivatives with ytterbium(II) reagent is reported. From a synthetic point of view, a general, efficient, and experimentally simple one-pot method for the preparation of 3-substituted 2-oxindoles was developed.

  The asymmetric synthesis of the 3-allyl-3-hydroxyoxindole skeleton was accomplished in yields up to 99% via a metal-free and enantioselective allylation of isatins (90–96% ee) using BINOL derivatives as catalysts and an optimized allylboronate. This methodology was applied at a gram-scale to the synthesis of the natural product (R)-chimonamidine.

• Catalytic Cascade: Efficient Synthesis of Cyclohepta[b]indoles and Cyclohepta[b]indole‐Indoline Conjugates via RCM, Hydrogenation, and Acid‐Catalyzed Ring Expansion

  DOI：10.1002/chem.202401059

  日期：——

  Efficient catalytic assembly for cyclohepta[b]indoles is achieved through sequential transformations: ring-closing metathesis, catalytic hydrogenation, and acid-catalyzed ring expansion. Ring closing metathesis (RCM) and hydrogenation of oxindoles yield spirocyclohexane-3-oxindoles. A subsequent spontaneous ring expansion-aromatization sequence, catalyzed by either Lewis or Brønsted acid, results in
