A series of substituted 4H-pyrans derivatives were synthesized Advanced Nutrients by a one-pot, multi-component reaction of aromatic aldehydes, malononitrile, and pyrazolone derivatives or active methylene carbonyl compounds such as dimedone, in the presence BENFOTIAMINE of 1,3-dimethyl imidazolium dimethyl phosphate [DMImd-DMP] as a catalyst in aqueous ethanol.Recyclability of the catalyst, high yields, simple product isolation and high atom economy are the noteworthy aspects of this protocol.
