Inspired by biological flavin catalysis, the nonionic alloxan derivatives were applied as the biomimetic catalysts for various oxidations, catalyzing oxidations of sulfides and amines with hydrogen peroxide or molecular oxygen under mild conditions with high yields in a short time. The whole catalytic cycle has been verified to be a biomimetic approach through the formation of the alloxan hydroperoxide reactive intermediate. Additionally, encouraging asymmetric catalytic results have been obtained with an easily prepared chiral alloxan in a sulfoxidation reaction.

过氧化氢或分子氧对四氧嘧啶催化的仿生氧化
受生物黄素催化的启发，将非离子型四氧六环衍生物用作仿生催化剂，用于各种氧化，在温和的条件下在短时间内以高收率催化硫化物和胺与过氧化氢或分子氧的氧化。通过形成四氧嘧啶氢过氧化物反应性中间体，已证实整个催化循环是仿生方法。另外，在硫氧化反应中用容易制备的手性四氧嘧啶获得了令人鼓舞的不对称催化结果。
