  摘要：

  根据对视黄醇诱导的人早幼粒细胞白血病细胞 HL-60 的细胞分化的抑制活性，以及利用视黄酸受体（RARs）和 RXRs 在 COS-1 细胞中的转录活化试验，确定了几种二苯并二氮杂卓衍生物为新型视黄酸 X 受体（RXR）拮抗剂。4-(5H-2, 3-(2,5-二甲基-2,5-己酸)-5-正丙基二苯并[b,e][1,4]二氮杂卓-11-基)苯甲酸（HX603，6c）是一种 RXR 泛拮抗剂 HX600（6a）的 N-正丙基衍生物，具有 RXR 选择性拮抗活性。4-(5H-2, 3-(2, 5-dimethyl-2, 5-hexano)-5-methyl-8-nitrodibenzo[b, e][1, 4]diazepin-11-yl)benzoic acid (HX531, 7a) 和 4-(5H-10、11-二氢-5，10-二甲基-2，3-（2，5-二甲基-2，5-己氰基）-二苯并[b，e][1，4]二氮杂卓-11-基)苯甲酸（HX711，8b），它们也能抑制 RAR 激动剂 Am80 诱导的 RARs 的转录活化。这些化合物抑制了低浓度视黄醇激动剂 Am80 与 RXR 激动剂（视黄醇增效剂 HX600）联合诱导的 HL-60 细胞分化。这些结果表明，HX603（6c）和相关的 RXR 拮抗剂能抑制 RAR-RXR 异源二聚体和 RXR 同源二聚体的活化，这是与已知的 RXR 拮抗剂 LG100754（9）不同的显著特点。

  日期：2019.12

  Herein, we report the natural ligand quebrachitol (QCT) as a promoter for a Cu(II) catalyst, which is highly effective for N-arylation of various amines and related aryl halides. A series of diarylamine derivatives were obtained in high yields by using diethylene glycol (DEG) as both ligand and solvent. The C–N coupling reactions proceed under mild conditions and exhibit good functional group tolerance

  The first Negishi nickel-catalyzed stereospecific cross-coupling reaction of secondary benzylic esters is reported. A series of traceless directing groups is evaluated for ability to promote cross-coupling with dimethylzinc.
