Description

Application

This reagent was used to introduce a bulky tert-butyl dimethylsilyl group onto a cis-bis(alkenyl)oxirane facilitating a room temperature Cope rearrangement to a 2-CF3-4,5-dihydrooxepin.

Together with a thiolane promotes a rapid and efficient chalcogenide-Morita-Baylis-Hillman reaction.
