N-Substituted 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-benzimidazoles were conveniently accessed via microwave-assisted synthesis. Subsequent Suzuki–Miyaura cross-coupling with heteroaryl halides proceeded to give a wide variety of heteroaryl-substituted benzimidazoles.
通过微波辅助合成方便地获得N-取代的5-(4,4,5,5-四甲基-1,3,2-二氧杂硼硼烷-2-基)-1 H-苯并咪唑。随后,Suzuki-Miyaura与杂芳基卤化物进行交叉偶联,得到了各种各样的杂芳基取代的苯并咪唑。
