A family of stabilized munchnones bearing an acyl group at C4 have been prepared and studied in alkyne cycloadditionreactions. These reactions are highly regioselective, and the method represents a rapid and straightforward route to densely substituted pyrroles. Finally, the C4-stabilizing units can be further manipulated to furnish carboxylic acid and amide groups, or removed altogether to provide
