Catalyst free, Domino Knoevenagel/6π-electrocylization, Microwave, 2H-pyrans, Solvent-free.
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.
