highly efficient strategy for obtaining a series of chiral 2,4-disubstituted thiazolone derivatives with excellent diastereo- and enantioselectivities through the creation of carbon- and nitrogen-substituted quaternary carbon stereocenters. With the chiral tertiary amine-thiourea catalyst developed by our group, the reactions could be performed smoothly at 1 mol-% catalyst loadings without any additive
我们提出了一种高效的策略,通过创建碳和氮取代的季碳立体中心,获得一系列具有优异非对映选择性和对映选择性的手性 2,4-二取代噻唑酮衍生物。使用本课题组开发的手性叔胺硫脲催化剂,反应可以在1 mol-%的催化剂负载量下顺利进行,无需任何添加剂。初步生物学评价表明,这些类似物可以显着抑制体外细胞增殖。
