Method for preparing thiol compounds by coupling cysteine having the formula HS--CH.sub.2 --CH(NH.sub.2)COOH via and --S-- bridge to a hydrocarbon compound and subsequently reacting the cysteine conjugate obtained with .beta.-lyase to form the relevant thiol compounds. For instance it is possible to prepare the flavor p-mentha-8-thiol-3-one starting from pulegone as illustrated in the diagram below: ##STR1##
通过将具有公式HS-CH.sub.2-CH(NH.sub.2)COOH的半胱氨酸通过-S-桥耦合到碳氢化合物上,然后将得到的半胱氨酸共轭物与β-裂解酶反应以形成相关的硫醇化合物的制备方法。例如,可以从薄荷酮开始制备p-mentha-8-thiol-3-one,如下图所示:##STR1##
