Add time:09/05/2019 Source:sciencedirect.com
A simple and novel synthesis of polytrisubstituted-2-pyridones derivatives by the reaction of enamino esters and diethyl ethoxymethylenemalonate has been reported. The method provides a rapid synthetic route for the construction of 2-pyridones under catalyst- and solvent-free reaction conditions in moderate-to-good yields.
