A mild, general, and convenient palladium-catalyzeddirectarylation of the 5-position of azoles with aryl bromides, efficiently promoted by tetrabutylammonium acetate, is described. 1-Methylpyrazole, oxazole, and thiazole reacted at 70 °C in N,N-dimethylacetamide by using Pd(OAc)2 as the catalyst precursor. Electron-poor and -rich functional groups, including the free hydroxy group, are well tolerated

regioselective CH arylation of electron rich pyrazoles has been developed. New ligands and mild conditions (70–90 °C) have been identified for this transformation. An intramolecular application of the methodology provided a novel synthetic route for the regioselective synthesis of 1,5-dihydroisochromeno[4,3-c]pyrazoles and 1,5-dihydroisothiochromeno[4,3-c]pyrazoles.
已经开发出了一种用于富电子吡唑的钯催化区域选择性C H芳基化的方法。新的配体和温和条件(70–90°C)已被确定用于该转化。该方法的分子内应用1,5-二氢异色烯的区域选择性合成提供了一种新的合成路线[4,3- c ^ ]吡唑和1,5- dihydroisothiochromeno [4,3- Ç ]吡唑。
