COA of Formula: C9H9NO. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 2-Ethylbenzo[d]oxazole, is researched, Molecular C9H9NO, CAS is 6797-13-3, about Biomimetic Synthesis of Benzimidazoles, Benzoxazoles and Benzothiazole via the Group Transfer of Tetrahydrofolate Models. Author is Wen, Xueshan; Chen, Jianxin; Zhao, Yanqin; Chang, Xingmao; Ma, Jiachun; Zheng, Wenjun.
2-Substituted benzimidazoles, benzoxazoles I [R = Et, n-Pr, i-Pr, etc.; X = NH,O], and 2-cyclohexylbenzothiazole were prepared in good yields by biomimetic reaction of o-phenylenediamine/o-aminophenol/o-aminothiophenol with imidazolium iodides as tetrahydrofolate model compounds at the oxidation level of formate. The reaction probably involved nucleophilic addition to the C=N bond at the imidazolium ring followed a 1,3-H migration at imidazolidine intermediate and a salt elimination. This biomimetic synthesis method offers advantages such as good yields of products, easy work-up, mild reaction conditions without the use of oxidants, acid, catalyst or microwave irradiation
