Claisenrearrangement of β-hydroxy allylic ester dianions provides stereocontrolled access to three contiguous chiral centers on an acyclic framework; an unambiguous method has been developed for assessing diastereoselectivity.

Radicalcyclizations of 3-hydroperoxymethylhexa-1,5-diene occur exclusively at the C-1,C-2 double bond to afford 1,2-dioxolanes stereospecifically, whereas electrophile-induced cyclizations additionally yield products derived from attack at the C-5,C-6 double bond.
