rapidly afforded the desired, structurally diverse 1,5,7‐trisubstituted‐3‐pyridyl‐xanthones. An evaluation of insecticidal activity revealed that one of the synthesized compounds retained insecticidal activity against vetch aphid and green peach aphid. The observed insecticidal spectrum was similar to that of pyripyropene A. The developed template could be a valuable aid for future agrichemical development
从天然存在的吡啶并戊二烯A开始,为农业化学开发设计了一种易于获取的1,5,7-三取代-3-吡啶基-氧杂蒽模板。我们最初开发的Ag 2 CO 3介导的氧化环化使您可以随时使用关键支架1,5,7-三羟基-3-氯蒽酮。对骨架的四个取代基的化学和区域选择性顺序引入迅速提供了所需的,结构上不同的1,5,7-三取代-3-吡啶基-氧杂蒽酮。对杀虫活性的评价表明,合成的化合物之一保留了对紫etch蚜和桃桃蚜的杀虫活性。所观察到的杀虫光谱与吡啶并戊烯A相似。开发的模板可能对未来农业化学的发展提供宝贵的帮助。
