An efficient and environment-friendly method for the synthesis of 1,3-oxazine derivatives has been developed using the ultrasound-mediated condensation of 2-naphthol with formaldehyde and primary amines under solvent-free condition at room temperature in

Various 1,3-oxazine derivatives were synthesized in high yields, within shorter reaction times using PEG-400 as a safer medium/mediator. This synthetic route is exceedingly easy and avoids the use of acid/base catalysts.

Sodium hydrogen sulphate (NaHSO4), n-tetra butyl ammonium bromide (TBAB) as a phase transfer catalyst (PTC) in water, and 1-butyl-3-methyl imidazolium hydrogen sulphate [bmim]HSO4 as ionic liquid (IL) has been used as a mild reaction promoter for the cyclocondensation of formalin, β-naphthol and aromatic amines to afford respective 2,3-dihydro-2-phenyl- 1H-naphtho-[1,2-e] [1,3] oxazine derivatives. The present protocols are greener, high yielding and involved the nonchromatographic isolation procedure.
