A redox-active iminoquinone motif connected with π-delocalized pyrene core has been reported that can perform efficient two-electron oxidation of a class of substrates. The design of the mol. was inspired by the organic redox cofactor topaquinone (TPQ), which executes amine oxidation in the enzyme, copper amine oxidase. Easy oxidation of both primary and secondary alcs. such as benzylalc., hexanol, 1-phenylethan-1-ol, cyclohexanol, etc. happened in the presence of catalytic KOtBu, which could reduce the ligand backbone to its iminosemiquinonate form under photoinduced conditions. Moreover, this easy oxidation of alcs. under aerobic condition could be elegantly extended to multi-component, one-pot coupling for the synthesis of quinolines e.g., I and pyrimidines II (R1 = Ph, 2-methylphenyl, 1-naphthyl, etc.; R2 = Ph, 4-chlorophenyl, 2-thienyl, etc.; R3 = H, Cl, Me, Br, etc.). This organocatalytic approach is very mild (70°C, 8 h) compared to a multitude of transition-metal catalysts that have been used to prepare these heterocycles e.g., I and II. A detailed mechanistic study proves the intermediacy of the iminosemiquinonate-type radical and a critical hydrogen atom transfer step to be involved in the dehydrogenation reaction.
