Abstract
Abstract In this work, we studied the aluminum chloride catalyzed reaction of 1- benzenesulfonyl-1H-pyrrole with a series of eleven aroyl chlorides. The products formed were not isolated, but hydrolyzed to the target 3-aroylpyrroles in overall yields, usually, higher than 50%. However, in the cases with the π electron rich 1-phenyl-1H-pyrrole-3- carbonyl chloride and 1-methyl-1H-indole-3-carbonyl chloride significant C-2 substitution ...
