convenient, and efficient approach to the synthesis of penta-substituted pyrroles has been reported based on the multicomponent reaction. Solvent-free condition for the formation of enaminones from primary amines and alkyl acetoacetates and it's reaction with fumaryl chloride lead to the formation of pyrroles that have halide, CH2CO2H, ester functional groups, and two alkyl substitutions.
基于多组分反应,已经报道了新颖,方便且有效的合成五取代吡咯的方法。由伯胺和乙酰乙酸烷基酯形成烯胺酮的无溶剂条件以及与富马酰氯的反应导致形成具有卤化物,CH 2 CO 2 H,酯官能团和两个烷基取代基的吡咯。
