A mild and efficient protocol for the synthesis of vicinal tricarbonyl compounds from β-dicarbonyls in a single step using cerium(IV) ammonium nitrate as a catalytic oxidant is described. Ease of execution, wide substrate scope and the suitability for the synthesis of commercially important compounds like ninhydrin, alloxan and oxoline make this reaction particularly noteworthy.
Reduction of Vicinal Tricarbonyl Compounds by Reduced Nicotinamide Adenine Dinucleotide Model and Electron-Transport Systems

The reduction of vicinal tricarbonyl compounds such as alloxan (A) and ninhydrin (NY) with 1-benzyl-1,4-dihydronicotinamide (BNAH; NADH model) was investigated.In the reduction of A with BNAH, the radical anion (A-.Py+) of A as the 1-benzyl-3-carbamoylpyridinium salt and the dialuric acid (D) was obtained by one-electron and two-electron reduction,respectively.Similarly,hydrindantin (HDT) and 2-hydroxy-1,3-indandione (HID) were also afforded in the reduction of NY with BNAH.Further,the reductions of alloxantin (AT) and HDT with BNAH were performed to give D and HID,respectively.The reduction of lipoic acid (LA) and viologens (V2+) with BNAH, which could not be reduced without A or NY, proceeded smoothly in their presence,and they proved to be useful as mediators for catalytic reduction of LA and V2+.
