triflates to access axially chiral (Z)-diarylmethylidene indanones (DAIs). The chemical, physical, and biological properties of DAIs are unknown, despite their being structurally similar to arylidene indanones, primarily due to the lack of racemic or chiral methods. Through this work, we demonstrate a general and efficient protocol for the racemic as well as the atropselective synthesis of (Z)-DAIs. An unusual
我们描述了 β-酮烯醇三氟甲磺酸酯的第一个 atropselective Suzuki-Miyaura 交叉偶联,以获取轴向手性 ( Z )-二芳基亚甲基茚满酮 (DAI)。尽管 DAI 在结构上与亚芳基茚满酮相似,但其化学、物理和生物学特性尚不清楚,这主要是由于缺乏外消旋或手性方法。通过这项工作,我们展示了 ( Z )-DAI的外消旋和 atropselective 合成的通用和有效的协议。一个不寻常的分子内 Morita-Baylis-Hillman 反应被用于 β-酮烯醇三氟甲磺酸酯的 Z 选择性合成。
