The chemistry of pyrrolic compounds. V. b-Methoxy- and b-hydroxyporphyrins

Abstract

Making use of dipyrrylmethane intermediates, the preparation of l- methoxy-2,3,4,5,6,8-hexamethylporphin (V) is described. The attempted synthesis of the corresponding hydroxyporphyrin has yielded a ketonic tetrapyrrole which is presumably a tautomer of the desired compound. The structure of this material is discussed.
