ABSTRACT:
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##
