NEW PRODUTS FROM THE DECOMPOSITION OF 2-HYDROXY-1,4BENZOXAZIN-3-ONE (HBOA) A NATURAL LACTAM FROM CE- REALS AND THE 7-NITRODERIVATIVE (HNBOA)
(Sociedad Chilena de Química, 2000)
New produis from the decomposition of 2-Hydroxy-1,4benzoxazin-3-one (HBOA) a natural lactam from cereals and the 7-nitroderivative (HNBOA)
(2000)
The products 3-hydroxy-1,4-benzoxazin-2-one (5) and 5-nitro-2-aminophenol were isolated from the decomposition reaction of the title compounds in aqueous solutions. Two mechanisms are proposed for the formation of these products.
N-acylation of lactams derived from natural 2-benzoxazolinones and 1,4-benzoxazin-3-ones
(Sociedad Chilena de Quimica, 1999)
The N-acylation reaction of a series of lactams of biological interest, derived from 2-benzoxazolinones and 1,4-benzoxazin-3-one, with acetic anhydride has been studied. The reaction yields show the same tendency as that ...
Antimicrobial activity of cereal hydroxamic acids and related compounds
(1993)
Hydroxamic acids derived from 2,4-dihydroxy-1,4-benzoxazin-3-one or 4-hydroxy-1,4-benzoxazin-3-one inhibited the growth of Staphylococcus aureus, Escherichia coli and Candida albicans. On the basis of structure-activity ...
Electronic effects of asymmetric and meta-alkoxy substituents on the polymerization behavior of bis-benzoxazines
(Royal Society of Chemistry, 2020-01)
Three isomers of benzoxazine monomers based on m-alkoxyphenol and 4,4′-methylenedianiline were synthesized and successfully isolated by column chromatography. The molecular structures of benzoxazine monomers were confirmed ...

Hydroxamic acids derived from 2-hydroxy-2h-1,4-benzoxazin-3(4h)-one: Key defense chemicals of cereals
(2009)
Many cereals accumulate hydroxamic acids derived from 2-hydroxy-2H-1,4- benzoxazin-3(4H)-one. These benzoxazinoid hydroxamic acids are involved in defense of maize against various lepidopteran pests, most notably the ...
Reaction of a cyclic hydroxamic acid from gramineae with thiols

Inhibition of ATPase from chloroplasts by a hydroxamic acid from the gramineae
(1983)
-DIMBOA (2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one), a hydroxamic acid from the Gramineae involved in the resistance of cereals to aphids, inhibits. © 1983.
Analysis of the structure and the FT-IR and Raman spectra of 2-(4-nitrophenyl)-4H-3,1-benzoxazin-4-one. Comparisons with the chlorinated and methylated derivatives
(Elsevier Science, 2017-07)
In this work, the structural, topological and vibrational properties of the monomer and three dimers of the 2-(4-nitrophenyl)-4H-3,1-benzoxazin-4-one (NPB) derivative were studied combining the experimental FTIR and FT-Raman ...
