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.

Esters (mixed anhydrides) derived from aliphatic or alicyclic carboxylic acids (RCO2H) and thiohydroxamic acids 2 or 3 undergo a thermally or photochemically induced radical chain reaction to give sulphides 4 with loss of carbon dioxide.On irradiation at low temperature however, the chain reaction is essentially suppressed.Under these conditions moderate to good yields of dimers R-R are obtained from primary acids.The mechanistic and synthetic implications of these observations are discussed.
NEW DECARBOXYLATIVE CHALCOGENATION OF ALIPHATIC AND ALICYCLIC CARBOXYLIC ACIDS.

, p. 5777 - 5780 (2007/10/02)
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.
