Abstract

Treatment of 2,5-di-unsubstituted pyrroles (e.g. 10) with excess of Eschenmoser's reagent (N,N-dimethylmethyleneammonium iodide) affords 2,5-bis-(N,N-dimethylaminomethy)pyrroles (e.g. 7); reaction with a second 2,5-di-unsubstituted pyrrole (e.g. 8) gives pure porphyrin (e.g. 9) with identical substituents on opposite pyrrole sub-units. © 1994.
