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.
