✦ Synopsis
On Corrole Chemistry.
An Isomerization Study and Oxidative Cleavage of the Corrole Macroring to a Biliverdin Structure.
-Free monophenyl-substituted corroles are obtained by an isomerization reaction. Reaction of (I) with (II) in acetic acid leads to a mixture of two a,c-biladienes forming the corroles (III) and (IV). The use of trifluoroacetic acid only gives the symmetrical corrole (III). Moreover, the first example of molecular oxygen oxidation of the corrole macrocycle (VI) into an open chain tetrapyrrole structure (VII) is given.
