PEG‐400[poly(ethylene glycol‐400)] is used as a “green” recyclable solvent in the one‐pot synthesis of 2‐arylimidazo[1,2‐a]pyrimidines by reaction with ketones, [hydroxyl(2,4‐dinitrobenzenesulfonyloxy)‐iodo]benzene (HDNIB), and 2‐aminopyrimidine. Significant rate enhancements and improved yields have been observed.
PEG-400 [聚(乙二醇-400)]在与酮[羟基(2,4,4)反应的单罐合成2-芳基咪唑[1,2- a ]嘧啶中用作“绿色”可回收溶剂-二硝基苯磺酰氧基)-碘]苯(HDNIB)和2-氨基嘧啶。已经观察到速率显着提高和产量提高。
