WebOct 22, 2024 · In particular the oxidative phenolic couplings, wherein two or more molecules of a phenol become linked together, constitute an important class of reactions. Many biosynthetic pathways, for instance these leading to usnic acid, dinapionones, and vancomycin, proceed via the phenolic coupling [2], [3], [4]. WebPhenolic coupling reactions caused by one-electron oxidations. Oxidative phenolic coupling. Biosynthesis of the alkaloid narwedine (3) is known to involve oxidative phenolic couplingof norbelladine derivatives(1), but the usual oxidants for such coupling in vitro convert 1(R = H) into the oxomaritidine skeleton (4) rather than 3.
