We have developed a very short synthesis of tert-butyl-hydroxylated di-tert-butyl-4-hydroxybenzaldehyde in which the HBr-DMSO system is used as an effective oxidant (overall yield of 45% for the entire four-step process from 2-tert-butyl-p-cresol). We also accomplished the synthesis of a major metabolite of the antiarthritic drug candidate S-2474.
我们开发了一种非常短的叔丁基羟基化二叔丁基-4-羟基苯甲醛合成方法,其中将HBr-DMSO系统用作有效氧化剂(整个四步法的总收率为45%,从2 -叔丁基对甲酚)。我们还完成了抗关节炎药物候选药物S-2474的主要代谢产物的合成。
