Abstract

The previously unknown transformation of coproporphyrins to coprochlorins was achieved via reduction of coprohemins I and II with sodium in isoamyl alcohol to give the corresponding novel coprochlorins I and II. Preliminary mechanistic studies using DFT calculations suggested a reduction pathway leading first to the porphodimethene followed by rearrangement to the chlorin.
