1,3-Di-O-substituted derivatives of benzene-1,2,3,5-tetrol were prepared from 2-nitrophloroglucinol-1,3-dibenzenesulphonate, or other 1,3-di-O-substituted derivatives of 2-nitropholoroglucinol and 5-nitropyrogallol. The p-nitrophenols were reduced to the corresponding amines which were then oxidised by an improved method to the p-benzoquinones; these on reduction gave the products. The 1,3- and 2,5-dimethyl
1,3-二- ö取代由2- nitrophloroglucinol -1,3- dibenzenesulphonate制备苯-1,2,3,5-四醇的衍生物,或其它的1,3-二- Ö取代的2-衍生物硝基邻苯三酚和5-硝基邻苯三酚。所述p -nitrophenols被还原成相应的胺,其随后通过一种改进的方法,以所述氧化的p -benzoquinones; 这些减少给了产品。还已经制备了四醇的1,3-和2,5-二甲基醚,2,3,5-三甲基醚和四甲基醚。
