Abstract
Treatment of 2-acetoxymethylpyrroles with 2-unsubstituted pyrroles in either methanol or acetic acid containing a catalytic quantity ( p-sulphonic acid hydrate, affords high yields of the corresponding pyrromethanes. The reaction in methanol is modified to give an acceptable yield of the tripyrrane (15), a member of a class of compound of current biosynthetic interest.Keywords
