title: Highly regioselective ruthenium-catalyzed allylic alkylations of chelated enolates.
abstract: Ru-catalyzed allylic alkylations are a highly interesting alternative to Pd-catalyzed reactions. Ru complexes show a high tendency for regioretention, especially for branched and (Z)-configured substrates, and they do not undergo isomerization of the allyl intermediates formed. Therefore, (Z)-substrates conserve their olefin geometry, and a perfect chirality transfer is observed with optically active substrates.
