In this work, we accomplished the first total synthesis of chiral alkaloid pimprinol A and the facile construction of its natural congeners: pimprinine, pimprinethine, pimprinaphine, WS-30581A, WS-30581B, laboradorin 1, uguenenazole, balsoxine, texamine in one-pot from commercially available starting materials including amino acids. Further investigating into the mechanism revealed that this improved
在这项工作中,我们完成了手性生物碱嘧啶醇A的第一个全合成反应,并轻松构建了其天然同源物:嘧啶碱,嘧啶嘌呤,吡吡吗啡,WS-30581A,WS-30581B,拉巴多巴胺1,uguenenazole,balsoxine,texamine一锅从可商购的起始材料包括氨基酸中提取。对该机理的进一步研究表明,这种改进的转化是通过碘化,Kornblum氧化,缩合,脱羧,环化和氧化反应顺序的整合而实现的。
