smoothly with optically active acetylenic ω-keto esters to afford optically active allenicesters (ee >95%) in high yield. After protection of the hydroxyl group, the addition of morpholine followed by an acidic hydrolysis, quantitatively led to optically active bicyclic α,β-unsaturated ketones (ee >95%). By using this methodology, the formal synthesis of an iphionane sesquiterpene was achieved.
Additions of imine to Michael acceptors and are both highly selective processes. The observed stereocontrol of the newly created asymmetric centers in the resulting adducts strongly supportscyclic-liketransition states.
