通过肽偶联剂丙基膦酸酐(T3P)介导的Pictet-Spengler反应选择性合成5,6-二氢菲啶,5,6-二氢苯并[ c ] [1,8]萘啶及其完全芳构化的类似物
摘要:
已开发出一种新方法,用于通过丙基膦酸酐(T3P)介导的Pictet-Spengler反应选择性合成5,6-二氢菲啶,5,6-二氢苯并[ c ] [1,8]萘啶及其完全芳构化的类似物。使用毒性较小且易于获得的T3P的方法通常似乎更灵活,更有效地制备5,6-二氢菲啶衍生物,并且与制备吡啶的常规方法相辅相成。
Selective synthesis of 5,6-dihydrophenanthridines, 5,6-dihydrobenzo[c][1,8]naphthyridines and their fully aromatized analogues via the Pictet–Spengler reaction mediated by peptide coupling agent propylphosphonic anhydride (T3P)
A new method has been developed for the selective synthesis of 5,6-dihydrophenanthridines, 5,6-dihydrobenzo[c][1,8]naphthyridines and their fully aromatized analogues via the Pictet–Spengler reaction mediated by propylphosphonic anhydride (T3P). The method, which uses less toxic and readily available T3P, generally seems to be more flexible, efficient in the preparation of 5,6-dihydrophenanthridine
