An efficient reductive Claisen rearrangement, catalyzed by in situ generated copper hydride and stoichiometric in diethoxymethylsilane, has been developed. Yields of up to 95 ;% with good to excellent diastereoselectivities were observed in this reaction. Mechanistic studies showed that the stereospecific rearrangement proceeded via a chair transition state of (E)-silyl ketene acetals as intermediates and not via the copper enolates.
Catalyst versus substrate induced selectivity: Kinetic resolution by palladacycle catalyzed allylic imidate rearrangements

Making chairs: A kinetic resolution of allylic imidates by planar chiral palladacycles is described which is the result of high face selectivity for olefin coordination to the catalyst and inherent substrate selectivity. These studies confirm that planar chiral palladacycles mainly operate via (half)chair-like transition states/intermediates.
