The stereoselective total synthesis of the novel quinolizidine alkaloid (+)-epiquinamide is presented, starting from the amino acid l-allysine ethylene acetal. Key steps in the synthesis involved a highly diastereoselective N-acyliminium ion allylation and a ring-closing metathesis reaction to provide the bicyclic skeleton. [reaction: see text]
提出了新的喹oli嗪生物碱(+)-表喹酰胺的立体选择性全合成,该合成是从氨基酸I-赖氨酸亚乙基缩醛开始的。合成中的关键步骤涉及高度非对映选择性的N-酰基酰亚胺离子烯丙基化和开环复分解反应以提供双环骨架。[反应:看文字]
