Snail shell as a new natural and reusable catalyst for synthesis of 4H-Pyrans derivatives

A simple, efficient and general method for the synthesis of 4H-pyrans is established through a multi component cyclocondensation of aromatic aldehydes, malononitrile and ethyl acetoacetate or acetyl acetone using snail shell as a natural catalyst.
