  Investigations on Estrogen Receptor Binding. The Estrogenic, Antiestrogenic, and Cytotoxic Properties of C2-Alkyl-Substituted 1,1-Bis(4-hydroxyphenyl)-2-phenylethenes

  摘要：

  C2-Alkyl-substituted 1,1-bis(4-hydroxyphenyl)-2-phenylethenes were synthesized and assayed for estrogen receptor binding in a competition experiment with radiolabeled estradiol ([H-3]-E-2) using calf uterine cytosol. The relative binding affinity decreased with the length of the side chain R = H (3a: 35.2%) > Me (3b: 32.1%) > Et (3c: 6.20%); CH2CF3 (3d: 5.95%) > n-Pr (3e: 2.09%) > Bu (3f: 0.62%). Agonistic and antagonistic effects were evaluated in the luciferase assay with MCF-7-2a cells stably transfected with the plasmid ERE(wtc)luc. All compounds showed high antiestrogenic activity without significant agonistic potency. The comparison of the IC50 values for the inhibition of E2 (1 nM) documented the dependence of the antagonistic effects on the kind of the side chain: 3a (IC50 = 150 nM), 3b (IC50 = 30 nM), and 3f (IC50 = 500 nM) were weak antagonists, while 3c (IC50 = 15 nM), 3d (IC50 = 9 nM), and 3e (IC50 = 50 nM) were full antiestrogens and antagonized the effect of E2 completely. The most active compound 3d possessed the same antagonistic potency as 4-hydroxytamoxifen (40HT: IC50 = 7 nM) without bearing a basic side chain. 3d as well as all other 1,1-bis(4-hydroxyphenyl)-2-phenylalkenes were not able to influence the proliferation of hormone dependent MCF-7 cells despite the antagonistic mode of action. In this assay tamoxifen (TAM) and 40HT reduced the cell growth concentration dependent up to T/C-corr = 15% and 25%, respectively.

  铜催化的三氟甲基化引发的1,2，芳基自由基在α，α-二芳基烯丙基醇中的迁移

  摘要：

  在标题反应中，不仅对称的，而且不对称的α，α-二芳基烯丙基醇也被用作底物。许多芳烃甚至杂芳烃都经历了自由基1,2-芳基迁移（“叶绿素重排”）以产生α-芳基β-三氟甲基酮。在不对称的底物中，缺电子的芳基优先于富电子的芳基迁移支持自由基机理，这通过DFT计算得到了进一步证实。

  Despite the great potential of radical chemistry in organic synthesis, N‐heterocyclic carbene (NHC)‐catalyzed reactions involving radical intermediates are not well explored. This communication reports the three‐component coupling of aroyl fluorides, styrenes and the Langlois reagent (CF3SO2Na) to give various β‐trifluoromethylated alkyl aryl ketones with good functional group tolerance in moderate to high

  尽管自由基化学在有机合成中具有巨大潜力，但涉及自由基中间体的 N-杂环卡宾 (NHC) 催化反应尚未得到很好的探索。该通讯报道了芳酰氟、苯乙烯和 Langlois 试剂 (CF 3 SO 2 Na)的三组分偶联，通过光氧化还原/NHC 协同催化，以中等到高产率生成各种具有良好官能团耐受性的 β-三氟甲基化烷基芳基酮。烯烃酰基三氟甲基化通过羰基与苄基C-自由基的自由基/自由基交叉偶联进行。羰基自由基是通过原位形成的酰唑鎓离子的 SET 还原产生的，而苄基自由基则源自三氟甲基自由基加成到苯乙烯上。

  An electrochemical oxidative difunctionalization of allyl alcohols for the synthesis of β-trifluoromethyl ketones is achieved through a 1,2-migration process. A series of β-trifluoromethyl ketones can be facilely obtained utilizing CF3SO2Na as a radical source, eliminating the use of metals and sacrificial chemical oxidants. Importantly, this protocol not only realizes aryl migration but also offers
