A variety of 2-arylnaphtho[1,2-d]oxazole derivatives were efficiently synthesized in moderate to high yields by the reaction of aromatic aldehydes with 1-amino-2-naphthol derivatives in the presence of triethylamine in refluxing ethanol in air. Seven new 2-arylnaphtho[1,2-d]oxazole derivatives were obtained and characterized by the spectral data and elemental analysis. In addition, the X-ray crystal structures of 2-[4-(N,N-dimethylamino)phenyl]naphtho[1,2-d] oxzole (3d) and 1,1′-bis(naphtho[1,2-d]oxazol-2-yl)ferrocene (3n) have been determined.

三乙胺促进的2-芳基萘并[1,2- d ]恶唑衍生物的简便合成

在空气中回流的乙醇中，在三乙胺的存在下，通过芳族醛与1-氨基-2-萘酚衍生物的反应，可以中等至高收率有效地合成各种2-芳基萘[1,2- d ]恶唑衍生物。获得了七个新的2-芳基萘[1,2- d ]恶唑衍生物，并通过光谱数据和元素分析对其进行了表征。另外，2- [4-（N，N-二甲基氨基）苯基]萘并[1,2- d ]恶唑（3d）和1,1'-双（萘并[1,2- ]的X射线晶体结构已经确定了d ]恶唑-2-基）二茂铁（3n）。
