The first straightforward synthesis of 16-hydroxycapsaicin, 17-hydroxycapsaicin and 16,17-dehydrocapsaicin, the major aliphatic metabolites of capsaicin, is reported. The amidation of hept-6-enoic acid with vanillylamine hydrochloride, followed by olefin metathesis using 2-methylbut-3-en-2-ol as par...
