摘要

Treatment of ketone If with acid brought about migration of the acyl group specifically to the 3- position of the pyrrole ring. This structure is consistent with the observed 1.5% coupling between the pyrrole ring protons. In contrast to the N-alkyl compounds 1 which were converted by acid completely to isomer 2, heating either a 2-acylpyrrole (3) or a 3- acylpyrrole (4) bearing hydrogen on nitrogen in strong anhydrous acid gave rise to an ...
