Abstract

This paper describes the development of 4-hydroxy-2-oxo-1,2-dihydroquinoline-3-carboxylate compound as a heterocyclic enols containing a Michael acceptor so that it participates in an Ugi-type multicomponent condensation through a Smiles rearrangement in replacement of acid components. The new four-component containing 4-hydroxy-2-oxo-1,2-dihydroquinoline-3-carboxylate, aldehyde derivatives, amine derivatives and isocyanides process leads readily and efficiently to heterocyclic enamines. This report is an outstanding strategy for the preparation of new biologically structures containing peptidic or pseudo-peptidic with quinolin-2(1H)-one scaffolds.
