A strain of Aspergillusniger was used to prepare optically active gem-disulphide S-oxides 2 and 3 and the (s)-meso-disulphoxide 4. The structural assignment was made by intercorrelating the senses of NMR non-equivalence in pseudoasymmetric disulphoxides 4 and 5 of established configurations with the configurationally related monosulphoxides 2 and 3. The enantiomeric composition and absolute configurations
