between 2-naphthol, an aryl aldehydes and thioacetamide catalysed by p-toluenesulfonic acid under reflux conditions provided a simple and efficient one-pot route for the synthesis of 1-[aryl(thioacetamido)methyl]-2-naphtholderivatives in excellent yields.
three‐component, highly efficient and solvent‐free approach for the synthesis of known and new 1‐thioamido‐alkyl‐2‐naphthol derivatives was investigated. This was achieved via a one‐pot condensation by reacting arylaldehydes, 2‐naphthol, and thioacetamide in the presence of catalytic amount of 1,3,5‐trichloro‐1,3,5‐triazinane‐2,4,6‐trione (TCCA) and 1,3‐dichloro‐5,5‐dimethylhydantoin (DCDMH).
