marine alkaloids motuporamines A-C, as well as the uncertainty as to the position of the olefin within the ring of motuporamine C, led us to synthesize these compounds. The strategy utilized the ring-closing metathesis reaction to form the 14- and 15-membered rings and Michael addition and amidation chemistry to introduce the spermine-like unit. The syntheses, structure assignment verifications, and
[公式:见正文]海洋生物碱motuporamines AC的异常结构和生物学特性,以及motuporamine C环内烯烃位置的不确定性,导致我们合成了这些化合物。该策略利用闭环易位反应形成14和15元环,并通过迈克尔加成和酰胺化化学反应引入精胺样单元。描述了合成,结构归属验证以及烯烃在motuporamine C中的位置测定。
