Abstract
The Mac Donald-type 2 + 2 condensation of the readily available 5-mesityldipyrromethane with acenaphthenequinone leads to the trans (syn and anti) porphodimethenes, respectively, which, after treatment with KOH or NaOMe in THF and subsequent oxidation with air, yield the corresponding trans-8-carboxynaphthylporphyrins or their esters.Keywords
