We examined whether a protein could catalyze two-phase oxidation of formaldehyde dithioacetals with aqueous sodium metaperiodate and bovine serum albumin was found to be effective and give the corresponding S-oxides in optically active forms.

The optimal condition for transformation of a chloromethyl sulfide into the corresponding Grignard reagent (2) in a high yield are established and 2 is shown to react with various functional groups such as an alkyl halide, an aldehyde, and a sulfinic este

Enzymes present in the fungus Mortierella isabellina catalyse the transfer of an oxygen atom to the cyclic thioacetal 1,3-dithian and from 1,3-dithian 1-oxide, 1,3,5-trithian 1-oxide, and cis-1,3-dithian 1,3-dioxide.The oxidation of 1,3-dithian and the acyclic thioacetal bis-(p-tolylthio)methane to form the corresponding monosulphoxides occurred in the presence of growing cultures of Aspergillus foetidus and a Helminthosporium species.The degree and the preferred direction of stereoselectivity occurring during the asymmetric oxidation and reduction steps was deduced from the enantiomeric excess (e.e.) and absolute stereochemistry of the isolated 1,3-dithian 1-oxide and p-tolylthio-(p-tolylsulphinyl)metane.
