Abstract

This paper describes a simple and efficient method involving domino Knovenegal/6π electrocyclization for the preparation of a variety of 2H-pyrans using microwave irradiation under solvent-and catalyst-free conditions. This method offers the advantages of a green approach, high yields, and short reaction times. Sixteen compounds (9a-p) were obtained in good to excellent yields using the procedure. Key Words: Catalyst free, Domino ...
