Difunctionalization of activated alkenes, a powerful strategy in chemical synthesis, has been accomplished for direct synthesis of a series of β-keto sulfides and β-keto sulfones. The transformation, mediated by O2, proceeds smoothly in water and without any catalyst. Prominent advantages of this method include mild reaction conditions, purification simplicity, and gram-scale synthesis, underlining the practical utility of this methodology.
Regioselective synthesis of 5-(arylsulfanyl)- and 5-(benzylsulfanyl)-6- phenylsalicylates by one-pot cyclizations of 1,3-bis(silyloxy)buta-1,3-dienes with 2-(arylsulfanyl)- and 5-(benzylsulfanyl)-3-ethoxy-1-phenylprop-2-en-1-ones

5-(Arylsulfanyl)-6-phenylsalicylates were prepared by one-pot cyclizations of 1,3-bis(trimethylsilyloxy) buta-1,3-dienes with 2-(arylsulfanyl)-3-ethoxy-1- phenylprop-2-en-1-ones.

Attempted fluorination of β-ketosulfides using Selectfluor resulted only in the isolation of the corresponding diaryl disulfides, presumed to arise by decomposition of an unstable fluorinated intermediate. However, fluorination of β-ketosulfones using Selectfluor under anhydrous conditions does allow the isolation of both mono-and difluorinated products in moderate to good yields.
