Abstract
Addition of nucleophiles such as dimethylsulfoxonium methylide and (Bu
OOLi)-O-t to the conjugate enyne sulfones 4-7, 11-14, 27-28 and 31 occ
urs at the beta-position to the phenylsulfonyl group to give the corre
sponding cyclopropanes 15-17 and 19-22 and the oxiranes 33-38 in high
yields. The thermal reactions of vinyloxirane 36 show an oxy-Cope rear
rangement to give 2-phenylsulfonylphenol 39.
