The CuI/CuII and CuI/CuIII catalytic cycles have been subject to intense debate in the field of copper-catalyzed oxidative coupling reactions. A mechanistic study on the CuI/CuII redox proc

An organocatalytic Cloke-Wilson rearrangement of cyclopropyl ketones to 2,3-dihydrofurans is exploited utilizing the homoconjugate addition process. With 1,4-diazabicyclo[2.2.2]octane as the catalyst, the rearrangement in DMSO at 120 °C proceeded in gener

Contrary to the general observation that thermally and photochemically induced cyclopropyl ketone to dihydrofuran arrangements take place with partial loss of the stereochemical identity of the starting cyclopropane, a characteristic shared by the closely related vinylcyclopropanes and vinyloxiranes, a case of totally stereospecific, alumina-assisted cyclopropyl ketone to dihydrofuran rearrangement at room temperature was observed.
