, p. 5321 - 5328 (2007/10/02)
The stereoselective preparation of EE 1-benzenesulfonyl-1,3-dienes is described.Michael addition and Diels-Alder cycloaddition of these compounds are reported.
FACILE ROUTE TO 1-PHOSPHORYL- AND 1-SULFONYL-1,3-DIENES VIA PALLADIUM-CATALYZED ELIMINATION OF ALLYLIC ACETATES

The palladium(II)-catalyzed chloroacetoxylation of 1,3-dienes is employed to prepare 1-chloro-4-acetoxy-2-alkenes which are then transformed into 1-phosphoryl- or 1-sulfonyl-4-acetoxy-2-alkenes respectively.Elimination of acetate is promoted by palladium(
Synthesis with Sulfones (n0XXX) : Stereoselective Synthesis of Arenesulfonyl-1,3-dienes.

Basic treatment of allylic 1,1-disulfones gives 1-arenesulfonyl 1,3-dienes.Condensation of aldehydes with lithiated allylic sulfones and in situ acetylation of the alkoxide thus formed followed by basic elimination of acetic acid leads to EE 2-arenesulfon
