摘要

Abstract An efficient and convenient synthesis of 1, 3-oxazine derivatives has been achieved by the one-pot, multicomponent condensation of α-or β-naphthol, an aniline and formaldehyde using thiamine hydrochloride (VB 1) as a versatile biodegradable and reusable catalyst in water as a universal solvent.
