An efficient access to vicinal dioxoalkanoates, one of structural elements of potent competitive inhibitors of hydrolytic enzyme, from 2,3-dihydroxyalkanoates has been developed, which features an one-step procedure with a mild oxidizing system using recyclable 2,2,6,6-tetramethylpiperidine-1-oxyl in combination with NaBrO2·3H2O or electrogenerated active bromine species as a real oxidant.
开发了一种高效的方法,从2,3-二羟基烷酸盐获取邻位二氧烷酸盐,这是一种强效竞争性水解酶抑制剂的结构元素。该方法具有一步法程序,并使用可回收的2,2,6,6-四甲基哌啶-1-氧与NaBrO2·3H2O或电生成的活性溴种作为实际氧化剂,且氧化条件温和。
