Abstract	Abstract: An efficient and novel one-pot synthesis of 3,4-dihydro-3-substituted-2 H -naphtho[2,1- e ][1,3]oxazine derivatives from 1-naphthol, various anilines and formalin at room temperature stirring. The six-membered N,O-heterocyclic skeleton was constructed via 1-benzyl-3-methyl imidazolium hydrogen sulphate [bnmim] [HSO 4 ] promoted Mannich type reaction. Keywords : 1,3-oxazines; ionic liquid; Mannich type reaction; multicomponent reaction. 1. Introduction Multicomponent reactions (MCRs), defined as one pot reactions in which at least three functional groups join through covalent bonds, have been steadily gaining importance in synthetic organic chemistry. 1-4 The reagents employed may be different molecules or they may be different molecules or they may be different functional groups of the same reagent. Speed, diversity, efficiency and environmental amiability are some of the key features of this class of reactions. Ionic liquids (ILs) have aroused considerable interest over the past decade due to their wide variety of properties. In this regard, they can be used as solvents and reaction supports.
