text] A newly developed strategy for construction of eight-membered carbocycles via [6 + 2] annulation that involves the combination of beta-alkenoyl acylsilanes and a vinyllithium derivative is described. A unique feature of this annulative approach is that it enables in one operation and a stereoselective manner construction of eight-membered ring systems containing useful functionalities for further
[反应:见正文]描述了一种新开发的策略,该策略通过[6 + 2]环构法构建八元碳环,该方法涉及β-链烯基酰基硅烷和乙烯基锂衍生物的组合。这种环形方法的独特之处在于,它可以一次操作和立体选择性地构建八元环系统,该系统包含有用的功能性,可以从容易获得的六碳和二碳组分中进一步合成精制。
