We report the synthesis of orthogonally functionalized naphthalenes from simple, commercially available indanones in four steps. The developed method proceeds through a two‐step process that features a thermally induced fragmentation of a cyclopropane indanone with simultaneous 1,2‐chloride shift. Migration of the chloride substituent occurs in a regioselective manner to preferentially afford the para‐chloronaphthol
我们报告了由简单的,可商购的茚满酮在四个步骤中合成正交官能化的萘。所开发的方法通过两步过程进行,该过程以热诱导的环丙烷茚满酮的裂解为基础,同时发生1,2-氯离子的转移。氯取代基的迁移以区域选择性方式发生,优先提供对氯萘酚的取代方式。所获得的萘酚是通用的构建基块,可以对其进行选择性修饰,并用于有效构建生物活性分子。通过高度收敛的逆合成键断开,可以有效合成有效的抗癌天然产物查拉汀。
