, p. 951 - 955 (2021/02/03)
A conceptually novel method for the preparation of pyrrole is described by electrochemical-oxidation-induced intermolecular annulation via enamines. In a simple undivided cell, based on a sodium acetate-facilitated, polysubstituted pyrrole derivations has been facilely synthesized under external oxidant-free condition. This electrosynthetic approach providing an environmentally benign protocol for C?C bond cross-coupling and oxidative annulation, which features unparalleled broad scope of substrates and practicality.

With visible light irradiation of a catalytic amount of Ir(ppy)3 at room temperature, a number of N-aryl enamines were transformed into their corresponding indoline products in good to excellent yields without requiring any extra additives. This is the first example of the synthesis of indolines via the intramolecular cyclization of enamines under visible light irradiation.
A facile, chemoselective and eco-friendly solid phase synthesis of enaminones catalyzed by L-Proline
Bhupathi, Raja S.,Devi, B.Rama,Dubey
experimental part, p. 5521 - 5524 (2012/07/13)
A facile and chemoselective method for the synthesis of enaminones by the reaction of aromatic primary amines with various β-ketoesters in the presence of L-proline as activator under solid phase is described. The reactions are promoted by the catalyst in short time (5-6 min) under ambient conditions, without any side products.
