Triacylamines with Cs symmetry have been explored in asymmetric organocatalysis, leading to the development of a novel catalytic enantioselective desymmetrization of prochiral triacylamines by methanolysis under the catalysis of chiral pseudopeptidic guanidine–guanidinium salt having a weakly coordinating anion. This organocatalytic methodology provides an effective approach to the synthetically useful
已经在不对称有机催化中探索了具有C s对称性的三酰基胺,从而在具有弱配位阴离子的手性假肽胍-胍盐的催化下通过甲醇分解开发了一种新的催化对映选择性去对称化前手性三酰基胺。这种有机催化方法为合成有用的具有 1,5-二羰基部分的手性酰亚胺酯提供了一种有效的方法,其合成潜力已在两种 GABA 类似药物的不对称合成中得到体现,( R )-巴氯芬·HCl 和 ( S )-普瑞巴林。
