Sulfoxide and sulfone intermediates 7 and 15, respectively, were employed to synthesize synthons 3 and 4, which are readily converted to the naturally occurring (2S,3R,4(E))-sphingosine 1 and (2S,3R)-sphinganine 2.

Irradiation with a tungsten lamp of mixed anhydrides (e.g. 8) derived from aliphatic or alicyclic carboxylic acids and N-hydroxy-2-pyridine thione 3 in the presence of a disulphide, diselenide or ditelluride gives the corresponding chalcogenide (e.g. 9, 10, or 11) in high yield.The process involves a radical decarboxylation followed by SH2 reaction of the intermediate carbon radical on the dichalcogenide.

Thiohydroxamic-carboxylic mixed anhydrides can be decarboxylated in the presence of diaryl disulphides, diselenides and ditellurides to give sulphides, selenides and tellurides respectively in reasonable to good yield.
