Reported is the first organocatalytic asymmetric 1,3‐alkyl shift in alkyl aryl ethers for the synthesis of chiral 3,3′‐diaryloxindoles using a chiral Brønsted acid catalyst. Preliminary results showed that each enantiomer of the 3,3′‐diaryloxindole, and a racemic mixture, showed different antiproliferative activities against HeLa cell lines by using an MTT assay.

烷基芳醚中的催化对映选择性1,3-烷基转移：光学活性3,3'-二芳基吲哚的高效合成

报道了使用手性布朗斯台德酸催化剂合成手性3,3'-二芳基吲哚的烷基芳基醚中的第一个有机催化不对称的1,3-烷基转移。初步结果显示，通过使用MTT分析，3,3'-二芳基吲哚的每个对映异构体和外消旋混合物对HeLa细胞系均表现出不同的抗增殖活性。
