Heteronucleophiles reagents react with &y-epoxy sulfones 1 at the y-position in the presence of Ti(OPf), or magnesium halides to afford regioselectively y-functionalixed @-hydroxy sulfones 2. With soft nucleofiles such as sodium axide, triphenylphosphine, or sodium benxethiolate the reaction takes p
