Novel dehydrative ring transformation of 1-alkyl-3-aroylpyrrolidines into 1-alkyl-2-aryl-3-methylpyrrole derivatives
Abstract
Poly-functionalized pyrroles 4, 5 and 6 were prepared in a good to high yield by a dehydrative ring transformation of 3-aroylpyrrolidine derivatives 1, 2 and 3 in ethylene glycol at 130 °C.
