Aromatic oxazines were first synthesized in 1944 by Holly and Cope [6] through Mannich reaction from phenols, formaldehyde and amines. They first proposed the 3,4-dihydro-2H-1,3-benzoxazine structure from the condensation of formaldehyde with o-hydroxybenzylamine. From the1950s to the 1960s, Burke et al. synthesized many benzoxazines and naphthoxazines [7] for the purpose of antitumor activity test. Reiss et al. investigated the polymerization of monofunctional benzoxazines with and without phenol as an initiator, resulting in linear polymers under 4000 molecular weight [8].

Derivatives of [1,3]-oxazine play a significant role in the theoretical organic chemistry and biologically active compounds. They show interesting interactions and can be used as chemotherapy agents. Dihydro-1,3-oxazine skeletons can be formed in proteins as they are converted into polypeptides.[1–4] Multi-component reactions (MCRs) have been frequently used by synthetic chemists as a facile means to generate molecular diversity from bifunctional substrates that react sequentially in an intramolecular fashion.[5]
