Under control: The first example of chiral amino phosphine catalysts for the title reaction between vinyl ketones and N‐sulfonyl‐1‐aza‐1,3‐dienes has been developed. Under ambient conditions, this protocol provides straightforward access to densely functionalized, enantioenriched tetrahydropyridines with high levels of sterecontrol in good to excellent yields.
下控制:手性氨基膦催化剂乙烯基酮类之间的反应标题的第一个例子Ñ磺酰基-1-氮杂-1,3-二烯已经研制成功。在环境条件下,该方案可提供对高功能性,对映体富集的对映体富集的四氢吡啶类化合物的直接访问,并具有高水平的立体异构控制,产率高至优异。
