Asymmetric oxidation of 1,2-diols, aminoalcohols, and aminoaldehydes in the presence of copper(II) triflate and (R,R)-Ph-BOX was accomplished by electrochemical method using Br− as a mediator. This oxidation was applicable to kinetic resolution of racemic cis-cycloalkane-1,2-diols, aminoalcohols, and aminoaldehydes to afford optically active compounds with good to high enantioselectivity.
在铜的存在下的1,2-二醇,氨基醇,氨基醛和不对称氧化(II),三氟甲磺酸和(- [R ,- [R)-Ph-BOX通过使用溴电化学方法来实现-作为介体。该氧化适用于外消旋的顺式-环烷烃-1,2-二醇,氨基醇和氨基醛的动力学拆分,以提供具有良好至高对映选择性的旋光化合物。
