Yamazaki, Masao,Guha, Samar Kumar,Ukaji, Yutaka,Inomata, Katsuhiko
experimental part, p. 740 - 753 (2009/04/10)
The stereochemistry of nucleophilic addition of amines to (E)-l-tosyl-l,3-butadiene was investigated. The Z/E ratios of the resulting allylic sulfones varied with amines, solvents, temperature, and concentration. When diethylamine was reacted in low conce

, p. 381 - 396 (2007/10/03)
It was found that the desulfonylation reaction of α,α-dialkylated (E)-allylic sulfones with a base preferentially affords the sterically unfavorable (Z)-alkadienes. The relative degree of the "syn-effect", which is herein defined as an effect which stabil
Synthesis of Allyl and Dienyl Sulphones via Iodosulphonylation of Conjugated Dienes
Barluenga, Jose,Martinez-Gallo, Jose M.,Najera, Carmen,Fananas, Francisco J.,Yus, Miguel
, p. 2605 - 2610 (2007/10/02)
The iodosulphonylation of conjugated dienes with sodium or mercury(II) toluene-p-sulphinate and iodine yields δ-iodoalkenyl sulphones stereoselectively.These compounds undergo stereospecific dehydrohalogenation to afford dienyl sulphones and nucleophilic
