8-Azaflavin was synthesized for the first time, and it was found that 8-azaflavin is much more reactive (>104) than 3,10-dimethylisoalloxazine for oxidation of thiols in aqueoussolution. Catalytic efficiency for disulfides synthesis was also examined under aerobic conditions.

Several bis-flavins linked at 10,10′-positions of isoalloxazine rings were synthesized. The reactivity of each flavin of a bis-flavin was found to be considerably influenced by another intramolecular flavin moiety, depending on the conformation of the bis-flavin.

Abstract The microwave-enhanced synthesis of 10-substituted isoalloxazines is achieved rapidly (˜4 min) and in good yield (>80–95%) via the cyclocondensation of 2-substituted aminoanilines with alloxan or N-methylalloxan monohydrate in the presence of acidic alumina or montmorillonite clays (KSF and K10).
