Novel benzoxazine-based aglycones block glucose uptake in vivo by inhibiting glycosidases. [PDF]

open access: yesPLoS 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

2-(4H-1,3-Benzoxazin-2-yl)phenol [PDF]

open access: yesActa 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.

Synthesis of Chiral 1,4,2-Oxazaphosphepines

open access: yesMolecules, 2015
Synthesis and structural characterization of 1,4,2-oxazaphosphepines is described. The 1,4,2-oxazaphosphepines were obtained from reaction of chiral 1,3-benzoxazines with dichlorophenylphosphine or triethyl phosphite.

Experimental and theoretical studies of benzoxazines corrosion inhibitors

open access: yesResults 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.

Simple and Selective Synthesis of 1,3-Benzoxazine Derivatives

open access: yesOriental Journal Of Chemistry, 2012
A simple and selective synthesis of 1,3-benzoxazine-2,4-dione and 4-methylene-1,3benzoxazine-2-one derivatives is reported from the reaction of Schiff bases and triphosgene. The selective synthesis of those 1,3-benzoxazine derivatives were found to be dependent on the type of substituents present on the Schiff base.

Towards Bio‐Based Benzoxazines (2015–2025): A Critical Review of Renewable Building Blocks, Formaldehyde‐Free Aldehydes, and ECHA Hazard Landscape

open access: yesPolymers for Advanced Technologies, Volume 37, Issue 8, August 2026.
ABSTRACT This review provides a critical overview of research on fully bio‐based benzoxazines over the period 2015–2025. A bibliometric analysis based on the Web of Science database is used to map how the field has evolved and to identify the renewable building blocks that have been most widely adopted.

Chiral (Stereoselective) Drugs, Asymmetric Synthesis, and Racemic Resolution Methods

open access: yesChirality, Volume 38, Issue 7, July 2026.
Chirality is crucial in drug development since both biological targets in the organism and the majority of pharmaceutical compounds are chiral. The synthesis and resolution of chiral compounds are critical steps while developing chiral drugs. Asymmetric synthesis and racemic resolution are the two most common methods for obtaining enantiopure drugs ...
