towards the synthesis of epoxydiynes which represent an unusual structural feature of the neocarzinostatin chromophore. A number of different routes to these epoxydiynes have been explored with varying success. Ultimately a concise and convergent approach was developed, which involved the addition of an allenyl zinc bromide to propargylic ketones/aldehydes followed by epoxide formation. This new protocol
我们在本文中介绍了我们对环氧二炔的合成所做的最新努力,该化合物代表了新carcarinostatin发色团的非同寻常的结构特征。已经探索了许多通往这些环氧二炔的不同途径,并取得了不同的成功。最终,开发出了一种简洁且收敛的方法,该方法涉及将炔丙基溴化锌添加到炔丙基酮/醛中,然后形成环氧化物。这个新的协议使我们能够合成一个完全精制的环氧二炔,这将为我们的研究在NCS生色团的全合成中找到应用。
