Method for preparing thiol compounds by coupling cysteine having the formula HS-CH₂-CH(NH₂)COOH via an -S- bridge to a hydrocarbon compound and subsequently reacting the cysteine conjugate obtained with β-lyase to form the relevant thiol compounds. For instance it is possible to prepare the flavour p-mentha-8-thiol-3-one starting from pulegone as illustrated in the diagram below:

硫醇化合物的方法:通过-S-桥将式为 HS-CH₂-CH(NH₂)COOH 的半胱
氨酸与烃化合物偶联,然后将得到的半胱
氨酸共轭物与 β-裂解酶反应生成相关的
硫醇化合物。 例如,如下图所示,可以从 pulegone 开始制备对
