Green and Efficient One-Pot Synthesis of 2-Amino-3-phenylsulphonyl-4H-chromenes under Solvent-Free Conditions
A green and convenient method for the synthesis of 2-amino-3-phenylsulphonyl-4H-chromenes by a one-pot three-component condensation of 1-naphthol, phenylsulphonylacetonitrile and aromatic aldehydes under solvent-free conditions using potassium phosphate tribasic trihydrate as an efficient catalyst is described. The reaction of 1-naphthol with phenylsulphonylacetonitrile and various aromatic...
متن کاملAmmonium-type Basic Ionic Liquid; 2-(2-Hydroxyethoxy)ethaneammonium Formate: Promote Green and Efficient Multicomponent Tandem Synthesis of 4H-pyrans and 4H-chromenes
A facile, convenient, green and environmentally benign one-pot three-component synthesis of poly-functionalized 4H-pyrans and 4H-chromenes is described. A basic ionic liquid 2-(2-hydroxyethoxy)ethaneammonium formate was found to be an efficient catalyst or catalytically active solvent for the synthesis of those important classes of heterocyclic compounds.
متن کاملOne-pot three component synthesis of 2-amino-4H-chromenes under green and high efficient conditions
A simple, mild and high efficient procedure for one pot three component synthesis of 2-amino 4-H chromene derivatives was studied. The reaction was performed in water using aryl aldehydes, malononitrile and resorcinol, phloroglucinol or naphthole in the presence of N-methyl D-glucamine (Meglumine) as a green high efficient catalyst. The reaction was studied in thermal, microwave (MW) and ultras...
