An easily prepared cinchona alkaloid derivative was found to be an effective organocatalyst in a direct, enantioselective aza-Mannich addition. By establishing a quaternary carbon stereocenter, a series of modified chiral 2-(ethylthio)-thiazolone derivatives have been obtained with excellent diastereo- and enantioselectivities. And these derivatives have been found to show anticancer activities against
发现容易制备的金鸡纳生物碱衍生物在直接,对映选择性氮杂-曼尼希加成中是有效的有机催化剂。通过建立季碳立体中心,已获得了一系列具有出色的非对映异构和对映选择性的改性手性2-(乙硫基)-噻唑酮衍生物。并且使用MTT分析法已发现这些衍生物显示出对五种不同癌细胞系的抗癌活性。
