N-Methyl-3-acylpyrroles were synthesized via a multicomponent reaction of dimethylacetylene dicarboxylate (DMAD), N-methylhydroxylamine and acylchlorides in the presence of KHCO3. For comparison both conventional and microwave protocols were examined in this procedure. The reaction is clean and gives the products in good to excellent yields under conventional heating conditions at 40 ºC in anhydrous dichloromethane.
N-甲基-3-酰基吡咯是通过在KHCO3存在下,由二甲基乙炔二羧酸酯(DMAD)、N-甲基羟胺和酰氯进行多组分反应合成的。为了进行比较,本程序同时考察了传统加热法和微波加热法。在无水二氯甲烷中,40ºC下采用传统加热条件,反应干净,产物收率良好至优秀。
