A synthetic sequence to the benzo[j]fluoranthene nucleus is described. Crucial steps of the procedure include a Suzuki coupling between appropriately substituted 2-bromo-acenaphthylene-1-carbaldehydes and 2-formylbenzeneboronates followed by McMurry ring closure. The synthesis represents a new approach to the benzo[j]fluoranthene ring system and specifically provides a method for the rapid preparation
描述了苯并[ j ]荧蒽原子核的合成序列。该过程的关键步骤包括在适当取代的2-溴-ena基-1-甲醛与2-甲酰基苯硼酸酯之间进行Suzuki偶联,然后进行McMurry闭环。该合成代表了苯并[ j ]荧蒽环系统的一种新方法,并特别提供了一种快速制备不同取代的衍生物的方法。按照这一策略,对最近分离出的天然产物苯并[ j ]荧蒽-4,9-二醇进行了首次全合成。
