The synthesis of new indazolone and pyrazolone derivatives starting from methyl anthranilate type substrates is presented. This general approach constitutes a novel and advantageous alternative for the synthesis of the target heterocycles, which implies the use of the environmentally friendly oxidizer PIFA. The synthetic design includes the oxidation of N-arylamides by the hypervalent iodine reagent
提出了从邻氨基苯甲酸甲酯型底物开始合成新的吲唑酮和吡唑啉酮衍生物。该通用方法构成了用于合成目标杂环的新颖且有利的替代方法,这意味着使用了环境友好型氧化剂PIFA。合成设计包括通过高价碘试剂将N-芳基酰胺氧化为相应的N-酰基硝酸镍离子,该分子可以被胺部分分子内捕获,从而通过形成新的N–N单键提供标题化合物。
