Abstract: The present work describes an efficient, green, and direct approach for the synthesis of amido alkyl naphthols via one-pot multicomponent solvent-free reaction (MCR) of substituted aromatic aldehydes, β-naphthols, and urea by the use of easily available, non-toxic, and cost-effective Lewis acid catalyst magnesium sulphate (MgSO4.7H2O). The important characteristics of this reaction include the following: eco-friendly and mild reaction conditions, excellent yields of the products, shorter reaction time, economically cheaper and environmentally friendly catalyst MgSO4.7H2O. Also, clean reaction, non-column purification, and operational simplicity are some of the additional significant features of this approach. |
