In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Expeditious and efficient synthesis of benzoxazoles, benzothiazoles, benzimidazoles catalyzed by Ga(OTf)3 under solvent-free conditions, published in 2011-08-31, which mentions a compound: 6797-13-3, Name is 2-Ethylbenzo[d]oxazole, Molecular C9H9NO, Computed Properties of C9H9NO.
A new and efficient method for the synthesis of benzoxazoles, benzothiazoles, benzimidazoles by cyclocondensation of o-substituted aminoaroms. with ortho esters in the presence of catalytic amounts of Ga(OTf)3 under solvent-free conditions is presented. The remarkable features of this new protocol are high conversion, very short reaction times, cleaner reaction profiles under solvent-free conditions, straightforward procedure, and use of a relatively non-toxic catalyst.
