A library of 24 6-(5-oxo-1-phenylpyrrolidin-3-yl)pyrimidine-5-carboxamides 101,2; 1–12} was prepared by a parallel solution-phase approach. The synthesis comprises a five-step transformation of itaconic acid (11) into 1-methyl and 1-phenyl substituted 6-(5-oxo-1-phenylpyrrolidin-3-yl)pyrimidine-5-carboxylic acids 171,2} followed by parallel amidation of 171,2} with a series of 12 aliphatic amines 181–12} to afford the corresponding carboxamides 10 in good overall yields and in 80–100% purity.
通过平行溶液相方法合成了24种6-(5-氧代-1-苯基吡咯烷-3-基)嘧啶-5-羧酰胺101,2; 1–12}的库。合成过程包括将伊奈酸(11)经过五步转化为1-甲基和1-苯基取代的6-(5-氧代-1-苯基吡咯烷-3-基)嘧啶-5-羧酸171,2},随后对171,2}与12种脂肪胺181–12}进行平行酰胺化,最终以良好的总体产率和80–100%的纯度获得相应的羧酰胺10。
