corresponding (di)carboxylic acids using AZADOs and PhI(OAc)2 is described. 1,2-Diols and 2,3-diols as well as 1,2,3-triol gave one- or two-carbon-unit-shorter carboxylic acids. Internal vicinal diols also smoothly underwent one-pot oxidative cleavage to afford the corresponding dicarboxylic acids. Cyclic vicinal diols are converted to their corresponding open-form dicarboxylic acids.
描述了使用AZADO和PhI(OAc)2对邻二醇进行温和且易于使用的一锅氧化裂解为相应的(二)羧酸的方法。1,2-二醇和2,3-二醇以及1,2,3-三醇生成一个或两个碳单元短的羧酸。内部邻位二醇也顺利进行一锅氧化裂解,得到相应的二羧酸。环状邻位二醇被转化为其相应的开放形式二元羧酸。
