The total synthesis of decarboxyaltenusin (5’-methoxy-6-methyl-[1,1’-biphenyl]-3,3’,4-triol), a toxin produced by various mold fungi, has been achieved in seven steps in a yield of 31% starting from 4-methylcatechol and 1-bromo-3,5-dimethoxybenzene, where the longest linear sequence consists of five steps. The key reaction was a palladium-catalyzed Suzuki coupling of an aromatic boronate with a brominated
脱羧阿藤菌素(5'-甲氧基-6-甲基-[1,1'-联苯]-3,3',4-三醇)是一种由多种霉菌产生的毒素,经过七个步骤的全合成从4-甲基儿茶酚和1-溴-3,5-二甲氧基苯开始,产率高达31%,其中最长的线性序列由五个步骤组成。关键反应是芳族硼酸酯与溴化间苯二酚衍生物的钯催化铃木偶联反应。
