描述了一锅反应合成4,4 '-二芳基和4,4'-二杂芳基取代的2,2 '-联吡咯的方法。新的方法是基于2-三甲基甲锡烷基化吡咯的氧化偶联,不需要色谱法。这些2,2 '-联吡咯可作为前体快速合成2,7,12,17-四芳基卟啉。
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.
