ABSTRACT:
A method for preparing thiol compounds, comprising: (1) reacting cysteine by a non-enzymatical addition reaction with a compound having the formula (R.sub.1)(R.sub.2)C.dbd.C(R.sub.3)--CO--R.sub.4 via an --S-- bridge to form a cysteine conjugate, wherein the symbols R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent hydrogen or an optionally saturated and/or heterogeneous hydrocarbon group or wherein a combination of two groups selected from the group consisting of R.sub.1, R.sub.3 and R.sub.4, together with the carbon atoms to which the groups are bonded, form an optionally saturated and/or heterogeneous hydrocarbon ring system of five or six members; and (2) reacting the cysteine conjugate so obtained in a concentration of >1 mM conjugate with a microbial .beta.-lyase to form a thiol compound.
