A metal-free cross-dehydrogenative coupling of quinones with toluene derivatives has been established. A series of quinones were subjected to reaction with toluene derivatives in the presence of di-tertbutyl peroxide (DTBP) for direct synthesis of benzylquinones. The method exhibits good functional group tolerance, and desired products were obtained in moderate to good yields. Meanwhile, a radical
of the redox potentials that correlated with the redox cycling of both targets in the coupled assay. Our approach demonstrates that the antimalarial activity of 3‐benz(o)ylmenadiones results from a subtle interplay between bioactivation, fine‐tuned redox properties, and interactions with crucial targets of P. falciparum. Plasmodione and its analogues give emphasis to redoxpolypharmacology, which constitutes
