see text]. Stereocontrolled construction of the 12-membered diene and triene lactones 1, 2, and 3, characteristic of the antitumor agent oximidines I and II, are reported and were based on an intramolecular Castro-Stephens coupling for the construction of a cyclic enyne or dienyne followed by stereoselective reduction of the cyclic alkyne for introduction of the cis-olefin of the targets. A comparison
[结构:见文字]。据报道,立体控制结构的十二元二烯和三烯内酯1、2和3是抗肿瘤药肟亚胺I和II的特征,它们基于分子内的Castro-Stephens偶联,用于构建环烯或二烯通过立体选择性还原环状炔烃以引入目标的顺式烯烃。使用标准的宏观内酯化方法对该协议的有效性进行了比较。
