Atroposelective arene formation is an efficient method to build axially chiral molecules with multi-substituted arenes. Reported here is an organocatalyzed atroposelective arene formation reaction by an N-heterocyclic carbene (NHC) catalyzed formal [4+2] cycloaddition of conjugated dienals and α-aryl ketones. This study expands the synthetic potential of NHC organocatalysis and provides a competitive
阻转性选择性芳烃的形成是用多取代的芳烃构建轴向手性分子的有效方法。此处报道的是通过N-杂环卡宾(NHC)催化的共轭二烯醛和α-芳基酮的正式[4 + 2]环加成反应进行的有机催化的对映选择性芳烃形成反应。这项研究扩大了NHC有机催化的合成潜力,并为轴向手性配体,催化剂和其他功能分子的合成提供了竞争途径。
