Abstract. An efficient and green synthesis of 1-amidoalkyl-2-naphthols via one-pot three-component condensation of aromatic aldehydes, acetamide and 2-naphthol in the presence of catalytic amounts of glycerosulfonic acid in glycerol as a green solvent was elaborated. Also a simple method for the one-pot threecomponent synthesis of 2,3-dihydroquinazoline-4(1H)-ones using of isatoic anhydride, aldehydes and ammonium acetate in the presence of glycerol as a green catalyst and solvent was described. In this light we introduced the brilliant and valuable role of glycerol in the synthesis of 2,3-dihydroquinazoline-4(1H)-ones and 1-amidoalkyl-2-naphthols.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
