  摘要：

  The syntheses of the meso-1,2-dialkyl-1,2-bis(3'-hydroxyphenyl)ethanes [alkyl substituent: CH3 (19), C2H5 (20), C3H7 (22), C4H9 (23), i-C4H9 (24), and C5H11 (25)] and of d,l-3,4-bis(3'-hydroxyphenyl)hexane (21) are described. In vitro these compounds inhibited the [3H]estradiol receptor interaction competitively, exhibiting Ka values between 0.20 x 10(9) (20) and 0.11 x 10(6) M-1 (24). In vivo the meso compounds reduced the estrone-stimulated mouse uterine growth; the most effective compounds were 20, 22, and 23 (53, 50, and 45% inhibition, respectively). Compounds 20 and 22-24 showed weak estrogenic activity in the mouse uterine weight test and in the vaginal cornification test. Compounds 19 (NSC-297169), 20 (NSC-297170), and 22 (NSC-297171) exhibited a dose-dependent growth inhibition on the MCF-7 human breast tumor cell line (10(-6) to 10(-9) M). These compounds also showed a marked dose-dependent inhibition on the DMBA-induced, hormone-dependent mammary carcinoma of the Sprague-Dawley rat corresponding to their association constants.

  photoredox catalysis. Mechanistic studies suggest that the observed selectivity was due to different active states of Ni(I) and Ni(0) modulated by Ru- and Ir-based photoredox catalysts, respectively. The ability to access different organometallic oxidation states via photoredox catalysis promises to inspire new perspectives for synergistic transition-metal-catalyzed divergent synthesis.

  发散性合成代表了直接访问源自相同原料的不同分子支架的强大策略。通常通过配体控制来实现通过过渡金属催化获得不同终产物的途径。我们在本文中证明了使用乙烯原料和可商购的芳基卤化物通过镍和光氧化还原的协同组合以高度选择性的方式完成1,2-二芳基乙烷，1,4-二芳基丁烷或2,3-二芳基丁烷的发散合成。催化。机理研究表明，观察到的选择性是由于分别由基于Ru和Ir的光氧化还原催化剂调节的Ni（I）和Ni（0）的不同活性态引起的。
