The enantiomerically pure chlorins 19 and 21 were synthesised from tripyrrolic nickel complex rac-17 and pyrrole building blocks 12 and 16. The pyrroles are annelated with norbornane moieties which contain the chiral information as well as two different functionalities. The functional groups, namely a carboxylic acid ester and a carbonitrile group, of chlorin 21 finally allowed the formation of an
对映体纯的二氢卟酚19和21是由三吡咯镍络合物rac-17和吡咯结构单元12和16合成的。吡咯与降冰片烷部分退火,该降冰片烷部分含有手性信息以及两种不同的官能度。二氢卟酚21的官能团,即羧酸酯和甲腈基团最终允许在大四环的外围形成氨基酸官能团。通过使用肽化学原理,将两个二氢卟酚亚基连接在一起,形成了肽连接的二氢卟酚-二氢二聚体24,它模仿了自然光合作用反应中心的分子部分。
