A one-pot reaction for the synthesis of 4,4′-diaryl- and 4,4′-diheteroaryl-substituted 2,2′-bipyrroles is described. The new methodology is based on the oxidative coupling of a 2-trimethylstannylated pyrrole and does not require chromatography. These 2,2′-bipyrroles can be used as precursors in a expeditious synthesis of 2,7,12,17-tetraaryl-porphycenes.
描述了用于合成4,4'-二芳基-和4,4'-二杂芳基取代的2,2'-联吡咯的一锅法反应。新的方法基于2-三甲基甲锡烷基化吡咯的氧化偶联,不需要色谱。这些2,2'-联吡咯可用作2,7,12,17-四芳基卟啉的快速合成中的前体。
