Using a carbenoid rearrangement to introduce the conjugated acetylenic framework, a series of triynols has been synthesized in five steps from 1,4-butynediol. Several of the triyne alcohols are known natural products and others are glycosylated analogues. This route avoids the use of terminal diynes as precursors, which can be unstable and/or difficult to prepare. It is therefore procedurally attractive in comparison to more traditional routes such as the Cadiot-Chodkiewicz and Sonogashira coupling reactions.
通过使用卡宾类重排引入共轭炔烃框架,已从1,4-丁炔二醇合成了一系列三炔醇,经过五个步骤。其中一些三炔醇是已知的天然产物,其他则是糖苷化类似物。这条路线避免了使用不稳定和/或难以制备的末端二炔作为前体。因此,与更传统的反应路线,如Cadiot-Chodkiewicz反应和Sonogashira偶联反应相比,这种方法在程序上更具吸引力。
