In the biosynthesis of sterols an enzyme-catalyzed demethylation is achieved via a stepwise oxidative transformation of alcs. e.g., 1-(4-methoxyphenyl)cyclodecan-1-ol to olefins e.g., 4-(OCH3)C6H4C(O)(CH2)7CH=CH2. The overall demethylation proceeds through two sequential monooxygenation reactions and a subsequent dehydroformylative saturation To mimic the desaturation processes observed in nature, photoredox proton-coupled electron transfer (PCET) and cobaloxime chem. were successfully integrated for the acceptorless dehydrogenation of alcs. The state-of-the-art remote and precise desaturation of ketones RC(O)(CH2)3CH=CH2 [R = 4-(tert-butoxy)phenyl, phenanthren-9-yl, 1-benzothiophen-2-yl, etc.] proceeds efficiently through the activation of cyclic alcs. I using bond-dissociation free energy (BDFE) as thermodn. driving force. The resulting transient alkoxyl radical allows C-C bond scission to generate the carbon-centered radical remote to the carbonyl moiety. The key intermediate is subsequently combined with cobaloxime photochem. to furnish the alkene. Moreover, the mild protocol can be extended to desaturation of linear alcs. as well as aromatic hydrocarbons. Application to bioactive mols. and natural product derivatives is also presented.
