Abstract

Different types of corroles and porphyrins are synthesized from substituted aldehydes and pyrrole. The current synthetic method involves iodine as catalyst and proceeds at room temperature itself. By varying the amounts of reactants (i.e., pyrrole and aldehydes), the corrole and porphyrins were obtained in good to excellent yields. These products were characterized by ¹H-NMR, UV-visible, and HRMS techniques. The reaction approach utilizes the readily available pyrrole and substituted aldehydes as starting materials and makes this reaction highly attractive in diversity-oriented synthesis.

以碘为催化剂合成介孔取代的卟啉和卟啉

摘要

由取代的醛和吡咯合成不同类型的克罗尔和卟啉。当前的合成方法涉及碘作为催化剂，并且本身在室温下进行。通过改变反应物（即吡咯和醛）的量，可以很好地获得优异的产率的corrole和卟啉。这些产物通过¹ H-NMR，UV-可见和HRMS技术进行表征。该反应方法利用容易获得的吡咯和取代的醛作为起始原料，并使该反应在面向多样性的合成中极具吸引力。
