a strategy of steric hindrance has been
successfully applied to the design of a series of novel chiral
diamines fromamino acids, and a series of robust and tunable
bulky chiral primaryamine catalysts have been developed and
applied in the direct diastereo- and enantioselective Michael
addition of substituted rhodanines to R,β-unsaturated ketones.
The reactions proceeded well, and a variety of different
enones were well tolerated, providing access to a wide range of
enantioenriched rhodanine derivatives, which were proven to
be valuable scaffolds in biochemistry and medicinal chemistry

立体位阻作为一种新方法,已经成功运用于一系列手性二胺类化合物的设计。我们发展了一系列大位阻的伯胺催化剂,并且把它们应用于导向迈克尔加成中的立体异构和对映异构体的合成,通过取代我们得到了 R,β-不饱和酮。反应进行很顺利,对不同的烯酮都有优良的兼容性,丰富了绕丹宁衍生物制备的方法。总之,这种方法在生物化学和医疗化学中发挥着重要的作用。
相逢,相识,相知
