MacDonald “2 + 2” condensation of a 1,2′-dipyrrylmethane dialdehyde with a 2,2′-dipyrrylmethane afforded a neo-confused porphyrin in 55% yield. In addition, a novel dihydroporphyrin with two appended pyrrolic units was isolated and structurally characterized.
1,2′-dipyrrylmethane 二醛与 2,2′-dipyrrylmethane 的 MacDonald "2+2 "缩合得到了一种新混淆
卟啉,收率为 55%。此外,还分离出一种带有两个附加
吡咯单元的新型二氢
卟啉,并确定了其结构特征。
