A new strategy for the preparation of unsymmetrical 2,2′-bis(pyrrolyl)alkanes has been developed. It involved the condensation of pyrrole derivatives onto N-benzylhydroxylamines in the presence of HCl. This two-step procedure provided access to a wide variety of 2,2′-dipyrromethanes (3a–m). It has also been extended to the synthesis of tripyrromethanes 4a–d and of N-confused dipyrromethanes 6a–d.
已经开发了制备不对称2,2'-双(吡咯基)烷烃的新策略。它涉及到吡咯在存在下N-苄基羟胺上的衍生物盐酸。这个分两步的程序提供了对各种2,2'-二吡咯甲烷(3a–m)的访问。它也已扩展到三吡咯甲烷4a–d和N混淆的二吡咯甲烷6a–d的合成。
