Cohen, Victor Israel; Pourabass, Soraya published the article 《Synthesis of some benzimidazole, benzoxazole and benzothiazole derivatives. Action of aliphatic seleno esters on some o-phenylenediamine, o-aminophenol and o-aminothiophenol and their derivatives》. Keywords: benzimidazole; benzoxazole; benzothiazole; aliphatic seleno ester reaction; phenylenediamine cyclization seleno ester; phenol amino cyclization seleno ester; thiophenol amino cyclization seleno ester.They researched the compound: 2-Ethylbenzo[d]oxazole( cas:6797-13-3 ).Quality Control of 2-Ethylbenzo[d]oxazole. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:6797-13-3) here.
Reaction of RC(Se)OEt (R = Me, Me2CH, pentyl, Pr, Et) with o-C6H4(NH2)2, o-HOC6H4NH2, o-HSC6H4NH2 or their derivatives gave 30-94% I (R = H, Cl, Me; R2 = H, Me, Z = NH, O, S). The mass spectra and NMR of I were studied.
《Synthesis of some benzimidazole, benzoxazole and benzothiazole derivatives. Action of aliphatic seleno esters on some o-phenylenediamine, o-aminophenol and o-aminothiophenol and their derivatives》 provides a strategy for the preparation of materials with excellent comprehensive properties, which is conducive to broaden the application field of this compound(2-Ethylbenzo[d]oxazole)Quality Control of 2-Ethylbenzo[d]oxazole.
