The first example of enzyme-catalyzed dynamic covalent kinetic resolution of hemithioketals was demonstrated. This method involved the reversible nucleophilic addition of methyl thioglycolate to activated ketones in conjugation with lipase mediated lactonization, generating 1,3-oxathiolan-5-ones in high yields as well as high enantiomeric purities.
证明了半硫缩酮的酶催化动态共价动力学拆分的第一个例子。该方法涉及将巯基乙酸甲酯可逆亲核加成到活化的酮中,并与脂肪酶介导的内酯化结合,以高产率和高对映体纯度产生 1,3-oxathiolan-5-ones。
