1 - One-pot Synthesis of 2-amino-4H-chromene Derivatives as Potential Antimicrobial Agents using DABCO-CuCl Complex as an Effective CatalystJournal of Applied Chemical Research , شماره 4 , سال 14 , تابستان 2020A new and efficient synthesis of 2-amino-4H-chromene derivativeswhich have remarkable pharmacological properties is developed by one-pot three-component efficient reaction between aldehydes, malononitrile, andα or β-naphthol in MeOH as solvent using DABCO-CuC چکیده کاملA new and efficient synthesis of 2-amino-4H-chromene derivativeswhich have remarkable pharmacological properties is developed by one-pot three-component efficient reaction between aldehydes, malononitrile, andα or β-naphthol in MeOH as solvent using DABCO-CuCl complex as an effective catalyst at room temperature. The structures of synthesized compounds were characterized by techniques of IR,1H-NMR, Mass and elemental analysis. This method provides an efficient improved pathway for the synthesis of chromenes in the terms of excellent yields, short reaction times and reusability catalyst. پرونده مقاله -
