Enantiomerically pure 1,5-hexadiene-3,4-diol, derived from D-mannitol in a few steps, may serve as a starting material for enantiopure dihydropyrans and dihydrofurans bearing an unsaturated side chain which is amenable for further synthetic transformations. The synthesis relies on a ring size-selective ring-closing metathesis reaction of a triene. Most likely, a catalyst-directing effect of an allylic
