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.
描述了一个温和而有效的方案,该步骤使用硝酸铈(IV)铵作为催化氧化剂,一步一步从β-二羰基合成邻位三羰基化合物。易于实施,广泛的底物范围以及对合成重要的化合物(如茚三酮,四氧六环和氧杂环丁烷)的适用性使该反应特别引人注目。
