A novel method for the introduction of an oxy functionality at the C12-position of the benzo[c]phenanthridine skeleton was developed. The method was successfully applied to a biomimetic synthesis of macarpine (3) from oxychelirubine (15), which was easily derived from the corresponding protoberberine (9).
我们开发了一种在苯并[c]菲啶骨架的 C12 位引入氧基官能团的新方法。该方法被成功地应用于以氧白桦脂碱 (15) 为原料合成大果芸香碱 (3)的生物仿生法,而大果芸香碱 (3) 很容易就能从相应的原小檗碱 (9) 中提取出来。
