A practical method for the synthesis of lycorine-type alkaloids with cis-B/C ring structure has been developed. Based on the reactions of aminocyclization, palladium-mediated arylation and especially cyclopropyl ring-opening rearrangement, the synthesis of anhydrocaranine, (±)-γ-lycorane and putative (±)-amarbellisine was accomplished.
已经开发出一种实用的合成具有顺式-B / C环结构的lycorine型生物碱的方法。基于氨基环化反应,钯介导的芳基化反应,尤其是环丙基开环重排反应,完成了脱水caranine,(±)-γ-lycorane和推定的(±)-amarbellisine的合成。
