Polybenzoxazines, also called benzoxazine resins, are a class of polymers that are produced from the ring-opening polymerization of 3-phenyl-2,4-dihydro-1,3-benzoxazine monomers and its chemical derivatives. (wikipedia.org)
Epoxy and polyol resins, ethoxylate surfactants, amines as curing agents, benzoxazines, and phenolic and polyester resins are just some examples of resins made from cardanol. (cardolite.com)
Monomers1
The photoinitiated polymerization of olefinic monomers such as methyl methacrylate by using benzoxazines as hydrogen donor in conjunction with aromatic carbonyl compounds is another suitable method for the desired functionalization. (itu.edu.tr)
Derivatives2
A new method was developed to synthesize 2-amino derivatives of 3,1-benzoxazines and 3,1-benzothiazines on the basis of ะพ -(cyclopent- 1-en-1-yl)aniline by heterocyclization of phenyl- and allylurea and thiourea derivatives in the presence of CF 3 CO 2 H, H 2 O 2 , or Br 2 . (osi.lv)

Synthesis4
A chiral phosphoric acid (CPA) catalyzes a versatile transition metal/oxidant free synthesis of chiral 2 H -1,4-benzoxazines through enantioselective desymmetrization of prochiral oxetanes (30 examples) in very good yield and high enantioselectivity under mild reaction conditions.

Amine2
1,3-Benzoxazines can be synthesized by the Mannich reaction using a phenol, an amine, and formaldehyde. (wikipedia.org)
Modification of linear and branched poly(propylene amine)s via Mannich reaction yields the corresponding benzoxazine functional PPOs. (itu.edu.tr)
Chemical2
Benzoxazines are a group of isomeric bicyclic heterocyclic chemical compounds that consist of a benzene ring fused to an oxazine ring. (wikipedia.org)
Benzoxazine rings form the central chemical structure of a number of pharmaceutical drugs including, for example, apararenone, elbasvir, and etifoxine. (wikipedia.org)
Rings1
Chemically, ofloxacin has three condensed 6-membered rings made up of a fluorinated carboxyquinolone with a benzoxazine ring. (nih.gov)
