Microwave-assisted efficient synthesis of azlactones using zeolite NaY as a reusable heterogeneous catalyst

ABSTRACT

The efficient preparation of azlactones in the presence of zeolite NaY has been reported. This heterogeneous catalyst was used for efficient synthesis of azlactone derivatives with Ac2O as a condensing agent under microwave irradiation and solvent-free conditions. The present method offers the advantages of good yields, short reaction time, simple work-up, and catalyst reusability, which makes this method mild and eco-friendly.
