The synthesis of Ethyl 5(S),6-Epoxy-3(R)-(methoxymethoxy)hexanoate, a key chiral synthon for the β-hydroxy-δ-lactone portion of Mevinolin and Compactin, via a regiospecific ring opening of a tetrahydrofuran derivative by dimethylboron bromide, is described.

Beta-alkoxyacrylates were found to be exceptionally efficient radical acceptors in radical-mediated intramolecular cyclizations. For example, reaction of 5-bromo-2-pentanol with ethyl propiolate, tributylstannane-mediated radical cyclization, and hydrolysis yielded (+/-)-(cis-6-methyltetrahydropyran-2-yl)acetic acid, a known component of civet.
