A new four-step procedure for the synthesis of 2,5-diformylpyrrole from hexane-2,5-dione was developed. The oxidation reaction of substituted 2,5-dialkylpyrroles with cerium(IV) ammonium nitrate (CAN) has been studied in detail. It was found that the outcome of the reaction strongly depends on the substituents present on the pyrrole moiety and on the reaction conditions. N-Tosyl- and N-mesyl-protected
从己烷-2,5-二酮合成2,5-二甲酰基吡咯的新的四步法。详细研究了取代的2,5-二烷基吡咯与铈(IV)硝酸铵(CAN)的氧化反应。已发现反应的结果强烈取决于吡咯部分上存在的取代基和反应条件。N-甲苯磺酰基和N-甲磺酰基保护的2,5-二甲基吡咯和3,4-二碘-2,5-二甲基吡咯被氧化成相应的二醛,而2,5-二烷基吡咯在3和4位带有吸电子基团将其转化为相应的酮醚或单醛,而不是预期的二酮。 吡咯-氧化-醛-酮-磺酰胺
