Application of the semi-pinacol rearrangement towards the generation of alkenyl-substituted quaternary carbon centres

The semi-pinacol rearrangement has been carried out on 2-methyl-2,3-epoxy- cyclopentanone derivatives, generating alkenyl-substituted quaternary carbon centred aldols with a defined relative stereochemistry. The Royal Society of Chemistry 2006.

Regiodivergent 1,4 versus 1,6 asymmetric copper-catalyzed conjugate addition

(Chemical Equation Presented) Metal matters: A highly regiodivergent copper-catalyzed asymmetric conjugate addition to α,β and γ,δ Michael acceptors is described. Zinc and aluminum reagents afford the 1,6 adduct with good to moderate enantioselectivity in the presence of ligand 1 (see scheme). In contrast, Grignard reagents used with hydroxy imidazolium ligand 2 afforded the 1,4 adduct with excellent ee values.
