Neuartige Oxazin‐Synthese [PDF]

open access: possibleChemische Berichte, 1980
New Oxazine SynthesisThe dialkylcyanamides 2 react with derivatives of o‐chloro‐carboxylic acids 1 and 5a,b to give benzoxazine 3 and the benzothieno‐oxazines 6 and 7. The chloride 5c reacts with 2 to form the carbimidoyl chlorides 8.

Thermoresponsive Poly(2‐oxazine)s

Macromolecular Rapid Communications, 2011
AbstractThe monomers 2‐methyl‐2‐oxazine (MeOZI), 2‐ethyl‐2‐oxazine (EtOZI), and 2‐n‐propyl‐2‐oxazine (nPropOZI) were synthesized and polymerized via the living cationic ring‐opening polymerization (CROP) under microwave‐assisted conditions. pEtOZI and pnPropOZI were found to be thermoresponsive, exhibiting LCST behavior in water and their cloud point ...

Chromogenic Oxazines for Cyanide Detection

The Journal of Organic Chemistry, 2005
[reaction: see text] We have designed two heterocyclic compounds for the colorimetric detection of cyanide. The skeleton of both molecules fuses a benzooxazine ring to an indoline fragment and can be assembled efficiently in three synthetic steps starting from commercial precursors.

Insights into the isomerization of photochromic oxazines from the excitation dynamics of BODIPY–oxazine dyads

Physical Chemistry Chemical Physics, 2012
We synthesized five BODIPY-oxazine dyads in one to four synthetic steps from known precursors. They differ in the nature of the unsaturated spacer linking the oxazine photochrome to either the conjugated framework or the boron center of the BODIPY fluorophore.

1,3-Oxazine Derivatives

1963
Publisher Summary This chapter discusses the methods of preparation and chemical properties of 1,3-oxazine derivatives. One of the derivatives discussed is tetrahydro-1,3-oxazines. The methods employed for the preparation of tetrahydro-1,3-oxazines include cyclization, hydrogenation, or other addition to the double bond of unsaturated 1,3-oxazines ...
