  Synthesis of Isothiazoles and Isoselenazoles through Rhodium-Catalyzed Oxidative Annulation with Elemental Sulfur and Selenium

  摘要：

  A rhodium-catalyzed oxidative annulation of benzimidates with elemental sulfur for the direct construction of isothiazole rings is reported. The proposed reaction mechanism involving Rh(I)/Rh(III) redox is supported by a stoichiometric reaction of metallacycle species as well as DFT calculations. This method is also applicable to selenium cyclization to produce isoselenazole derivatives. The alkoxy substituent at C3 can be used for further functionalization of the azole core.

  Expeditious Synthesis of 2-Aryl Substituted Imidazolines and Imidazoles

  摘要：

  A versatile and efficient method for the synthesis of 2-aryl substituted imidazolines and imidazoles bearing a carboxylate group on C-4 is reported. Three different synthetic pathways were explored, compared and optimized. The selected procedure involves condensation of methyl 2,3-diaminopropionate with different imino ethers. The ring closure, monitored by LC-MS analysis, was facilitated by heating at reflux in ethanol leading to increase the rate of cyclization.

  The first example of oxidant-free cobalt-catalyzed synthesis of five-membered spirocycles is reported from benzimidates and maleimides utilizing nitrobenzene as promoter. In contrast to previously known cobalt-catalyzed oxidative C–H functionalization reactions, this transformation occurs efficiently in the absence of oxidant and is accompanied by liberation of hydrogen. The spiro-lactams were readily
