tetrahydrofurans from readily available allylic diol and carbonyl components is reported. This synthesis is highly stereocontrolled and allows carbon side chains to be incorporated at each carbon. Enantiomerically pure tetrahydrofurans are readily prepared from chiral, nonracemic allylic diol precursors. The asymmetric synthesis of (+)-muscarine tosylate from the lactate-derived allylic diol 6a demonstrates that
