[structure: see text] An unprecedented V-shape (2.1.2.1) expanded porphyrin incorporating an extended pi-conjugated system is described. Its efficient synthesis relied on the use of a new peralkyl tetrapyrrolylquinoxaline building block that constitutes the ideal intermediate for the versatile preparation of new quinoxaline-containing macrocycles.
[结构:见正文]描述了一种空前的V形(2.1.2.1)扩展的卟啉,其中结合了扩展的pi共轭体系。它的有效合成依赖于使用新的全烷基四吡咯基喹喔啉构件,该构件构成了多功能制备新的含喹喔啉的大环化合物的理想中间体。
