Induction of apoptosis by benzoxazine analogues

2001
We have evaluated the possible apoptotic effect of benzoxazine (BO) derivatives. For that purpose, we tested the induction of apoptosis by 6-[1-hydroxy-2-(1H-1-imidazolyl)ethyl]-4-methyl-3,4-dihydro-2H-1,4-benzoxazin-3-one (FO4) and 6-[1-[(4-chlorobenzyl)oxy]-2-(1H-1-imidazolyl)ethyl]-4-methyl-3,4-dihydro-2H-1,4-benzoxazin-3-one (FO5) BO analogues in ...

Synthesis and Thermal Stability of Benzoxazine Nitroxides

The Journal of Organic Chemistry, 2011
A new class of stable nitroxides (aminoxyls) having a 1,4-benzoxazine structure were synthesized and the corresponding thermal stability tested. All derivatives were stable in the entire range of temperatures employed, except those having a benzyl or a tert-butyl group at the β-position with respect to the aminoxyl function, which underwent radical ...

Studies of benzoxazines 16*. Synthesis and reactivity of 2,4-substituted 4H-3,1-benzoxazines

Chemistry of Heterocyclic Compounds, 2012
A novel method has been developed for preparation of substituted 4H-3,1-benzoxazines via formation of tetrafluoroborates. The substitution of halogen in 2-(α-haloalkyl)-4,4-diphenyl-4H-3,1-benzoxazines by NH and SH nucleophiles was performed. The effect of electrophilic substitution in the annelated aromatic ring in a series of 2,4-substituted 4H-3,1 ...

1,3-Oxazines and benzoxazines

1991
This chapter deals with the reviews published in the past decade dealing with 1, 3-oxazines. It includes a survey by Steglich on the uses of 1, 3-oxazin-6-ones, as versatile intermediates in heterocyclic synthesis. A more general summary of the chemistry and uses of “oxazinones” covering the period 1976-1985 are presented by Zakhs and coworkers.

Benzoxazine-modified asphalts

The use of polymers for modification of asphalt is an attempt to prolong the service life and improve the performance of asphalt particularly for road pavement applications. This research aims to study mechanical and thermal properties of asphalt modification by bisphenol A based benzoxazine resin.
