e, thiophene and furan derivatives with pyrrole in the presence of acid catalyst. The core-modified porphyrins were synthesized by acid catalyzed 3 + 1 condensation of modified tripyrrins with 2,5-bis(α-hydroxymethyl)-substituted pyrrole, thiophene or furan. This new process gives a single porphyrin isomer and overcome the synthetic problems associated with separation and purification of regioisomeric
发现在酸性催化剂存在下,通过2,5-双(α-羟甲基)吡咯,噻吩和呋喃衍生物与吡咯的缩合,可以得到简单的条件来得到改性的三吡啶衍生物。核心修饰的卟啉通过酸修饰的三联吡啶与2,5-双(α-羟甲基)取代的吡咯,噻吩或呋喃的3 + 1缩合反应合成。该新方法提供了单一的卟啉异构体,并克服了与分离和纯化区域异构体混合物相关的合成问题。
