Copper Hydride Catalyzed Reductive Claisen Rearrangements
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.

THERMAL O -> C REARRANGEMENT OF N-PHENYL-ALLYLIMIDATES
Properly substituted N-phenyl-allylimidates 1 are shown to undergo preferential O -> C sigmatropic rearrangement on heating.The diastereoselectivity of this reaction resembles the one observed in ortho ester Claisen rearrangements.
