Easy Access to Quinolin-2(1H)-ones via a One-Pot Tandem Oxa-Michael–Aldol Sequence
Résumé
An efficient strategy for the synthesis of a variety of quinolin-2(1H)-one derivatives has been developed. The reaction proceeded from cinnamide derivatives via a tandem reaction in the presence of NaOH to afford the corresponding 2- quinolin-2(1H)-one derivatives in good to excellent yields.
