An efficient and convenient synthetic methodology has been developed with which to
construct β-trifluoromethylthio- and seleno-α,β-unsaturated ketones through copper-mediated
trifluoromethylthio(seleno)lation of β-bromo α,β-unsaturated ketones. The corresponding
ketone products were isolated in moderate to good yields and were efficiently converted
into valuable alcohols.
Key words
