In this study, a novel asymmetricsynthesis of all-carbon quaternary stereogeniccentres is developed by the connection of three prochiral or achiral components--conjugated enones, organometallic compounds and vinyl esters--at the...

The [4 + 2] and [2 + 2] intramolecularcycloadditions to allenecarboxylates are strongly affected by conformational differences of the substrates in the transition state.
