The reactions of enamines with sulfoxides bearing α-hydrogens in the presence of a magnesium amide, generated in situ from the reaction of ethylmagnesium bromide with diisopropylamine, afforded the corresponding α-sulfenylalkylated ketones and aldehydes in isolated yields ranging from 39 to 76%. This procedure was successfully extended to the bis(methylthio)methylation with methyl (methylthio)methyl sulfoxide.
Chemoselective conjugate 1,4-reduction of α-oxoketene dithioacetals with zinc in acetic acid: Synthesis of β-oxodithioacetals
Rao, Ch. Srinivasa,Patro, Balaram,Ila, Hiriyakkanavar,Junjappa, Hiriyakkanavar
, p. 57 - 59 (2007/10/03)
Acyl ketene dithioacetals 1 and 3 undergo highly chemoselective conjugate 1,4-reduction with zinc in acetic acid to give β-oxodithioacetals 2 and 4 in high yields.
Regio- and chemoselective conjugate 1,4-reduction of α-oxoketene dithioacetals with sodium borohydride and sodium cyanoborohydride
Srinivasa Rao,Chakrasali,Ila, Hiriyakkanavar,Junjappa, Hiriyakkanavar
, p. 2195 - 2204 (2007/10/02)
Theα-oxoketene dithioacetals 1 are shown to undergo conjugate 1,4-reduction in highly regio- and chemoselective manner with sodium borohydride in acetic acid to afford the corresponding β-oxodithioacetals 5 in good yields. These results have been rational

Hevesi, L.,Nsunda, K. M.
, p. 6513 - 6514 (2007/10/02)
The title reactions have been carried out in high yield by reacting Lewis acid activated thio- and seleno-orthoformates with silyl enol ethers derived from aldehydes and ketones.
