摘要：

Acid catalysed ''3+1'' condensation of 1,6-cycloheptatrienedicarboxaldehyde with a tripyrrane dicarboxylic acid, followed by neutralization with triethylamine and oxidation with DDQ, afforded the cycloheptatrienyl porphyrin analog ''tropiporphyrin'' in good yields; this system favors porphyrin-like 18 pi delocalization pathways for both the free base and the related monocation.
