A simple and practical procedure for the oxidation of vinyl selenides into the corresponding selenones using Oxone in water at 60 °C has been reported. Structurally diverse phenyl vinyl selenones were oxidized under heterogeneous conditions without organi

The reaction of vinyl selenones with di-(-)-bornyl malonate and sodium hydride occurred with low diastereoselectivity and afforded a mixture of two diastereomeric cyclopropane derivatives in comparable yields. These, however, could be easily separated by chromatography. Removal of the bornyl group afforded highly enantiomerically enriched cyclopropanes. An example of the simple conversions of these cyclopropanes into useful cyclopropane α-amino acids is also illustrated. The syntheses of several vinyl selenides and selenones are also described.
COMPETITION BETWEEN VINYLIC SUBSTITUTION AND CONJUGATE ADDITION IN THE REACTIONS OF VINYL SELENOXIDES AND VINYL SELENONES WITH NUCLEOPHILES IN DMF

Vinyl selenoxides and vinyl selenones present a different reactivity towards thiolate or alkoxide anions in DMF.In the case of selenoxides the addition of the nucleophiles regioselectively occurs at the α-carbon leading to the formation of the vinylic sub
