In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called The conversion of mixed N,O-diacylated 2-aminophenols to 2-substituted benzoxazoles, published in 1999-05-01, which mentions a compound: 6797-13-3, mainly applied to acyl aminophenol cyclocondensation benzoxazole preparation; alkylbenzoxazole preparation; phenylbenzoxazole preparation, Quality Control of 2-Ethylbenzo[d]oxazole.
When N,O-diacylated 2-aminophenols that have different acyl substituents on nitrogen and oxygen are treated with p-toluenesulfonic acid in refluxing xylenes, mixtures of benzoxazoles are produced. The major product is the benzoxazole in which the substituent at the 2-position is derived from the acyl group on nitrogen. This product may arise from an unusual case of acid-mediated neighboring amido-group assisted hydrolysis.
From this literature《The conversion of mixed N,O-diacylated 2-aminophenols to 2-substituted benzoxazoles》,we know some information about this compound(6797-13-3)Quality Control of 2-Ethylbenzo[d]oxazole, but this is not all information, there are many literatures related to this compound(6797-13-3).
