Glycine catalyzed convenient synthesis of 2-amino-4H-chromenes in aqueous medium under sonic condition.
A one-pot three-component condensation of an aldehyde, malononitrile, and resorcinol has been achieved by ultrasound method. The reaction has been catalyzed by glycine in aqueous medium. This protocol afforded corresponding 2-amino-4H-chromenes in shorter reaction times, high yields and simple work-up procedures with the green aspects by avoiding toxic reagents.

6-chloro-3-hydroxy-2-phenyl-4-oxo-4H-1-benzopyran CHPB) has been used for the first time as an analytical reagent for the spectrophotometric determination of tungsten. The yellow colored W (VI) – CHPB complex has λmax at 420 nm, is extractable into chloroform from 0.04 – 0.32 M HCl medium containing 0.6 – 1.6 mL of 0.1% CHPB (in acetone). Tungsten (VI) in presence of several cations, anions and...
متن کاملAn unusual Me3SiI-promoted [4+2] annulation and reduction: an efficient approach to construct 4H-benzopyrans.
Me(3)SiI-promoted reaction of salicylic aldehydes with β-dicarbonyl compounds provided a facile way to construct 4H-benzopyrans in moderate to good yields. This tandem reaction proceeds with high efficiency through nucleophilic addition, silyl enol ether formation, substitution, reduction, and intramolecular nucleophilic cyclization.
متن کامل2-(4-Hydroxyphenyl)-3-methoxy-4H-chromen-4-one
In the title compound, C16H12O4, the substituent benzene ring and meth-oxy group are twisted relative to the 4H-chromene skeleton by 24.1 (1) and 61.3 (1)°, respectively. In the crystal, mol-ecules are connected by classical O-H⋯O and weak C-H⋯O hydrogen bonds, forming chains parallel to [201]. The 4H-chromene ring systems of adjacent mol-ecules are either parallel or inclined at an angle of 28...
