A Sm(II)-mediated, asymmetric, intermolecular ketyl-olefin addition employing α,β-unsaturated esters linked to resin through an ephedrine âchiral linkâ has been applied in a direct âasymmetric catch-releaseâ approach to γ-butyrolactones.

potential of a solid-phase asymmetric resin-capture-release strategy for high-throughput synthesis has been evaluated. Fukuzawa's Sm(ii)-mediated, asymmetric approach to gamma-butyrolactones was selected to illustrate the feasibility of such a process. Alpha,beta-unsaturated esters immobilised on an ephedrine chiral resin have been applied in an asymmetric approach to gamma-butyrolactones. Lactone
