a conceptually different approach, highly stereoselective 2-oxonia-Cope rearrangement reactions between rationally designed
nonracemic vinylogous aldolation synthons and aldehydes are described
to provide δ-hydroxy-α,β-unsaturated esters with
excellent enantioselectivities and, for the first time, unprecedented Z- and E-selectivities without the regioselectivity
issue.
