A concise synthesis of the Lycopodium alkaloid lycoposerramine Z is reported. Key to the strategy is a one-pot organocatalyzed Michael reaction followed by a domino Robinson annulation/intramolecular aza-Michael reaction promoted by LiOH, leading to enantiopure cis-decahydroquinolines.
本文报道了石松生物碱石松赛洛辛 Z 的简洁合成。该策略的关键是一锅法有机催化的迈克尔反应,然后是由 LiOH 促进的串联 Robinson 环化/分子内氮杂-Michael 反应,得到对映纯的顺式-十氢喹啉。
