Ninhydrin as a novel and efficient catalyst for the synthesis of ۲-amino-۴H-Pyran derivatives in aqueous media using

< p>Benzopyranes and their derivatives are of interest due to their wide range of biological and medicinal properties. In this study, ۲-amino-۴H-pyran derivatives were obtained through a one-step multi-component reaction of aromatic aldehyde, malononitrile and dimedone in the presence of ninhydrin as a catalyst in water with high efficiency and short time.
