摘要： 文献报道合成2,6-二芳基取代苯并[1,2-d;4,5-d']二(口恶)唑有两种方法,其一是2,5-二氨基对苯醌与芳香醛缩合,然后氧化,关环;其二是2,5-二氨基对苯二酚盐酸盐与酰氯缩合关环.

Abstract: In this paper a modified method of preparation of 2,6-disubstituted benzo-[1, 2-d;4,5-d']-bisoxazoles is reported.2,5-Diamino-quinone-1,4 was reduced with stannous chloride in hydrochloric acid. The product, 2,5-diamino-hydroquinone-l, 4 hydrochloride was then condensed with benzoic acid and substituted benzoic acids respectively in polyphos-phoric acid. Thus, 2,6-diphenyl benzo-[1,2-d;4, 5-d']-bisoxazole and eleven of its substituted phenyl derivatives were prepared.
