本文报道合成Pyrrolizidinone和Pyrrolizidine环系的新方法,即通过酰亚胺正离子14成环,然后经碳正离子15重排而成Pyrrolizidinone环系.采用这种方法,合成了六个新的Pyrrolizidinone及Pyrrolizidine生物碱类似物(1—6).
In this paper, a new method for the synthesis of Pyrrolizidinone and Pyrrolizidine ring systems is reported, in which Pyrrolizidinone ring systems are formed by the 14-membered ring of imide cations and rearranged by Cation-15. Six new Pyrrolizidinone and Pyrrolizidine Alkaloid Analogs (1-6).
