The HKR of racemic anti- or syn-3-substituted epoxy esters catalyzed by a Co(iii)salen complex provides ready access to the corresponding enantioenriched 3,4-disubstituted γ-butyrolactones and 3-substituted epoxy esters. This strategy has been successfully employed in the formal synthesis of biologically active 3,4-disubstituted piperidine derivatives, (-)-paroxetine and Ro 67-8867 and a natural product, (+)-eldanolide.
Stereoselective conjugate addition of aryl- And alkenylboronic acids to acyclic γ,δ-oxygen-substituted α,β-enoates

The substrate-controlled Rh1-catalyzed conjugate addition of aryl- and alkenylboronic acids to α,β-unsaturated esters which bear γ- and δ-oxygen substituents takes place in a highly anti diastereoselective fashion either when using γ-hydroxyl u
