  Convenient access to isoindolinones via carbamoyl radical cyclization. Synthesis of cichorine and 4-hydroxyisoindolin-1-one natural products

  摘要：

  An efficient and convenient access to 2-tert-butylisoindolin-1-ones via an oxidative radical cyclization process from stable carbamoylxanthates, derived from secondary tert-butylamines, is described. The proposed mechanism for this transformation involves, the generation of a carbamoyl radical, its cyclization to the aromatic system, and the dilauroyl peroxide (DLP) mediated rearomatization to generate the isoindolinone ring system. Additionally, the syntheses of cichorine and 4-hydroxyisoindolin-1-one natural products were carried out to underscore the synthetic potential of this xanthate-based carbamoyl radical-oxidative cyclization.

• A family of N-heterocyclic carbene-stabilized borenium ions for metal-free imine hydrogenation catalysis

  This manuscript probes the steric and electronic attributes that lead to “frustrated Lewis pair” (FLP)-type catalysis of imine hydrogenation by borenium ions. Hydride abstraction from (ItBu)HB(C6F5)22 prompts intramolecular C–H bond activation to give (CHN)2(tBu) (CMe2CH2)CB(C6F5)23, defining an upper limit of Lewis acidity for FLP hydrogenation catalysis.

• Carbamoyl radicals from carbamoylxanthates: a facile entry into isoindolin-1-ones
  作者：Germán López-Valdez、Simón Olguín-Uribe、Luis D. Miranda

  DOI：10.1016/j.tetlet.2007.09.142

  日期：2007.11

  It has been found that carbamoylxanthates derived from secondary t-butyl amines are stable compounds which function as efiicient sources of carbamoyl radicals. The carbamoylxanthates derived from t-butylbenzylamines can be efficiently transformed into 2- t-butylisoindolin-1-ones via an oxidative radical cyclization process. The carbamoylxanthates derived from N-t-butylamino olefins underwent the expected cyclization/xanthate-transfer process to afford the corresponding pyrrolidones and piperidones under thermally induced DLP fragmentation conditions and in the presence of catalytic Et3B in air, at room temperature.
