Experimental and theoretical studies of benzoxazines corrosion inhibitors
Results in Physics, 2017 2-Methyl-4H-benzo[d][1,3]oxazin-4-one (BZ1) and 3-amino-2-methylquinazolin-4(3H)-one (BZ2) were evaluated for their corrosion inhibition properties on mild steel (MS) in hydrochloric acid solution by weight loss technique and scanning electron microscopy.

Synthesis and preliminary bioassays of some bis -1,3 - benzoxazines [PDF]
Revista Colombiana de Química, 1990 Se hicieron ensayos preliminares con miras a establecer la posible actividad insecticida de cinco bis-l,3-benzoxazinas del tipo 3,3-etilen-bis(3,4-dihidro-6R-2H-1,3-benzoxazina). De cuatro de ellas (R= -F, -Cl,-Br,-I) se conocía su síntesis, mientras que la del compuesto R = -H se describe por primera vez.

Synthesis and Characterization of Bio-based Polybenzoxazine Hybrids From Vanillin, Thymol, and Carvacrol. [PDF]
Chem Asian JIn this study, we synthesized hybrid benzoxazines from the bio‐phenolic compounds—vanillin, thymol, and carvacrol— Jeffamine D‐230, and paraformaldehyde through a Mannich reaction. The thermal polymerizations of the hybrid benzoxazines were analyzed using differential scanning calorimetry (DSC).

2-(4H-1,3-Benzoxazin-2-yl)phenol [PDF]
Acta Crystallographica Section E Structure Reports Online, 2009 The title compound, C(14)H(11)NO(2), features an essentially planar mol-ecule, the r.m.s. deviation for the 17 non-H atoms being 0.035 Å. This conformation is stabilized by an intra-molecular O-H⋯N hydrogen bond that results in the formation of an S(6) ring.

Novel benzoxazine-based aglycones block glucose uptake in vivo by inhibiting glycosidases. [PDF]
PLoS ONE, 2014 Glycoside hydrolases catalyze the selective hydrolysis of glycosidic bonds in oligosaccharides, polysaccharides, and their conjugates. β-glucosidases occur in all domains of living organisms and constitute a major group among glycoside hydrolases. On the
