Alkylidene sulfones were prepared in moderate to good yields via direct alkylidenating reaction of ketones with geminal dibromomethyl sulfones promoted by the Sm/Sml2 system in the presence of a catalytic amount of TiCl4 under mild conditions.
"Syn-Effect" in the Conversion of (E)-Vinylic Sulfones to the Corresponding Allylic Sulfones
Hirata, Takaki,Sasada, Yoshihiro,Ohtani, Takashi,Asada, Takahiro,Kinoshita, Hideki,et al.
, p. 75 - 96 (2007/10/02)
It was found that (E)-vinylic sulfones preferentially afford (Z)-allylic sulfones as kinetically-controlled products by treatment with a base under mild conditions, while (Z)-vinylic sulfones give (E)-allylic sulfones.Such stereochemical relationship was
