A novel three‐component one‐pot reaction involving β‐naphthol, aldehydes, and urea promoted by TMSCl/NaI

Abstract

Abstract magnified image Amidoalkyl naphthol derivatives have been synthesized in good yields in a one‐pot condensation of β‐naphthol, aromatic aldehydes and urea in presence of TMSCl/NaI at room temperature. Ring closure of amidoalkyl naphthol derivatives occurred at 140°C to afford 1,2‐dihydro‐1‐arylnaphtho[1,2‐e] [1,3]oxazin‐3‐one derivatives. J. Heterocyclic Chem., (2010).
