So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Smith, Peter A. S.; Chou, Shang-Shing Peter researched the compound: 2-Ethylbenzo[d]oxazole( cas:6797-13-3 ).Recommanded Product: 2-Ethylbenzo[d]oxazole.They published the article 《Cyclization of phenyl azides with homoallylic or allylic ortho substituents and the consequences of triazoline fragmentation》 about this compound( cas:6797-13-3 ) in Journal of Organic Chemistry. Keywords: azide phenyl cyclization; allyloxyphenyl azide cyclization; thermolysis phenyl azide. We’ll tell you more about this compound (cas:6797-13-3).
Thermolysis at 110-20°of o-allyloxyphenyl azide and 14 derivatives substituted on the allyl group gave benzoxazines, dihydroazirinobenzoxazines, or 3-alkenylbenzomorpholines through fragmentation of intermediate triazolines. With substituted allyl groups, the geometrical isomers gave the same products in the same ratio, except in the case of o-(β,γ-dimethylallyl)phenyl azide. Rearrangement by Ph migrations occurred with the β-phenylallyl compound o-Allylphenyl azide, (o-azidophenyl)acetaldehyde, and o-[(cis-1-propenyl)oxy]phenyl azide required of 155-200° for thermolysis and yielded 2-methylindole, oxindole, and 2-ethylbenzoxazole, resp., by nitrene insertion.
Although many compounds look similar to this compound(6797-13-3)Recommanded Product: 2-Ethylbenzo[d]oxazole, numerous studies have shown that this compound(SMILES:CCC1=NC2=CC=CC=C2O1), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
