libraries using Rink amide resin is described. Thiazoles are assembled in a one-pot MCR of a thiocarboxylic acid, aldehyde, 3-(N,N-dimethylamino)-2-isocyanoacrylate with a resin-bound primary amine. Aliphatic and aromatic thiocarboxylic acids as well as aliphatic and (hetero-) aromatic aldehydes work in the reaction. Cleavage of the product yields the substituted thiazoles in reasonable to good purity.
描述了一种新的多组分反应(MCR),用于使用Rink酰胺树脂制备2-取代的噻唑文库。噻唑在硫代羧酸,醛,3-(N,N-二甲基氨基)-2-异氰基丙烯酸酯与树脂结合的伯胺的一锅式MCR中组装。脂肪族和芳香族硫代羧酸以及脂肪族和(杂)芳香族醛在反应中起作用。产物的裂解产生合理至良好纯度的取代的噻唑。
