  Palladium-catalyzed ortho-nitration of 2-arylbenzoxazoles

  摘要：

  An efficient and general protocol for palladium-catalyzed chelation-assisted ortho-nitration of 2-arylbenzoxazoles has been developed. This nitration exhibits high regioselectivity for the substrates, and the reaction could tolerate many functional groups such as F, Cl, Br, CH3, CH3O, affording ortho-nitration products in moderate to good yields. Moreover, some 2-arylbenzoxazole heterocyclic analogues proceed well under this catalytic system. Further studies have been performed to obtain insight into the mechanism. (C) 2015 Elsevier Ltd.

  The direct decarboxylative arylation of hetereoarenes with benzoic acids through a nickel-catalyzed sp2 C–H functionalization process was developed. This process provides the first examples of decarboxylative cross-coupling reactions with aromatic acids through nickel catalysis and tolerates a variety of functional groups. Moreover, this method provides efficient access to 2-aryl-substituted azoles

  通过镍催化的 sp2 C-H 功能化过程，杂芳烃与苯甲酸直接脱羧芳基化。该过程提供了通过镍催化与芳香酸进行脱羧交叉偶联反应的第一个例子，并且可以耐受各种官能团。此外，该方法提供了对 2-芳基取代唑的有效获取，2-芳基取代唑是天然产物、药用化合物和功能材料中的重要结构单元。
