Synthesis of Novel Thioamidoalkyl- and Thiocarbamidoalkyl Naphthols via a Three-Component Condensation Reaction Using Heterogeneous Catalyst of Ferric Hydrogensulfate
heterogeneous catalyst for the one-pot multicomponent reaction of β-naphthol, aromatic aldehydes, and thioamide derivatives to obtain the corresponding thioamidoalkyl naphthols. Various novel thioamidoalkyl naphthols and thiocarbamidoalkyl naphthols were synthesized in good yields from thioacetamide and thiourea. The heterogeneous nature of the catalyst made it reusable for further chemical reactions. GRAPHICAL
