2, (R)-BINOL, and 4 Å molecular sieves were used to induce enantioselectivity in inverse electron demand Diels-Alder reactions between pyrone-3-carboxylates and enol ethers. The critical dependence of the enantiomeric excesses on the nature of the molecular sieves (water content, trace elements) was investigated at length. Hence, in retrospect, our failure to reproduce Keck's best results by his method may have been caused by differences in the molecular sieves. Since molecular sieves are omitted in our protocol, the necessity of exploring which molecular sieves give best results is circumvented
