In the past three decades, the heterocyclic oxazine cores have been intensely concerned. Oxazine
derivatives are promising vital heterocyclic motifs. They are eminent for their synthetic potential
and extensive biological properties. Oxazines are versatile intermediates for the synthesis of a variety of
heterocycles and bifunctional compounds. Researchers have reported several synthetic approaches for
the preparation of oxazines. This review emphasises the recent approaches for the synthesis of oxazine
derivatives.
