Abstract
The Mac Donald-type 2 + 2 condensation of the readily available 5-mesityldi pyrromethane with acenaphthenequinone leads to the trans (syn and anti) por phodimethenes, respectively, which, after treatment with KOH or NaOMe in TH F and subsequent oxidation with air, yield the corresponding trans-8-carbox ynaphthylporphyrins or their esters.
