• A Rhodium-Catalyzed Cascade Cyclization: Direct Synthesis of<i>N</i>-Substituted Phthalimides from Isocyanates and Benzoic Acids
  作者：Xian-Ying Shi、Andrea Renzetti、Soumen Kundu、Chao-Jun Li

  DOI：10.1002/adsc.201300834

  日期：2014.3.10

  A rhodium(III)‐catalyzed amidation between benzoic acids and isocyanates via direct functionalization of an ortho CH bond followed by intramolecular cyclization is described. This cascade cyclization affords N‐substituted phthalimides in one step in 26–91% yields. The reaction is highly atom‐economical, since no theoretical waste except for water is generated in the reaction.

• Rh^III-Catalyzed C−H Olefination of Benzoic Acids under Mild Conditions using Oxygen as the Sole Oxidant
  作者：Quandi Jiang、Changlei Zhu、Huaiqing Zhao、Weiping Su

  DOI：10.1002/asia.201500601

  日期：2016.2

  Phthalide skeletons have been synthesized for the first time through a RhIII‐catalyzed C−H olefination of benzoic acids under mild conditions using oxygen as the sole oxidant. Aromatic acids bearing a variety of functional groups could react with diverse alkenes to afford the desired cyclized lactones or uncyclized alkenylarenes in moderate‐to‐excellent yields.
