本文报道合成Pyrrolizidinone和Pyrrolizidine环系的新方法,即通过酰亚胺正离子成环,然后经碳正离子重排而成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.

关键词: 苄基, 二元酮, 吡咯双烷生物碱, 并吡咯烷 P

Title compounds I (Z = H, OH; H, HCO2; O; Z1 = H, H; O) were prepared from 4-MeOC6H4CHO via N-acyliminium ion II.

Key words: BENZYL GROUP, DIKETONE, PYRROLIZIDINE ALKALOID, PYRROLIZINE P
