  Potential antiestrogens. Synthesis and evaluation of mammary tumor inhibiting activity of 1,2-dialkyl-1,2-bis(3'-hydroxyphenyl)ethanes

  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.

  The copper‐catalyzed carbomagnesiation (or hydrometalation) reaction of chiral cyclopropenylcarbinol derivatives, obtained by means of a kinetic resolution of secondary allylic alcohols, leads to an easy and straightforward preparation of enantiomerically pure alkylidenecyclopropane derivatives. The reaction mechanism is composed of a syn‐carbometalation followed by a syn‐elimination reaction. To gain

  通过仲烯丙醇的动力学拆分获得的手性环丙烯基甲醇衍生物的铜催化碳镁化（或加氢金属化）反应可以简单直接地制备对映体纯的亚烷基环丙烷衍生物。反应机理是顺式碳金属化，然后是顺式-消除反应。为了进一步了解碳金属化的反应机理，还实现了环丙基甲醇的非对映选择性形成，并且发现它对用于加成反应的有机金属物质的性质非常敏感。环丙醇也可以通过环丙烯基甲醇衍生物的非对映选择性还原来制备。最后，在温和条件下，将富含对映异构体的环丙烯基甲醇官能化为相应的乙酸酯或亚膦酸酯衍生物会导致各种对映异构体纯杂取代的亚烷基环丙烷。

  We report nickel-catalyzed cross-coupling of methoxyarenes with alkylmagnesium halides, in which a methoxy group is eliminated. A wide range of alkyl groups, including those bearing β-hydrogens, can be introduced directly at the ipso position of anisole derivatives. We demonstrate that the robustness of a methoxy group allows this alkylation protocol to be used to synthesize elaborate molecules by

  我们报告了镍催化的甲氧基芳烃与烷基卤化镁的交叉偶联，其中甲氧基被消除。广泛的烷基，包括那些带有 β-氢的烷基，可以直接在苯甲醚衍生物的 ipso 位置引入。我们证明甲氧基的稳健性允许该烷基化方案通过将其与传统的交叉偶联反应或氧化转化相结合来合成复杂的分子。这种方法的成功取决于使用烷基碘化镁，而不是氯化物或溴化物，这突出了卤化物在使用格氏试剂进行催化反应中的重要性。

  A series of 1- (2, 3, 4-trimethoxybenzyl) piperazine (trimetazidine) derivatives were prepared and tested for cerebral vasodilating activity. Almost all the compounds possess stronger activity than trimetazidine and among them, the γ-amino tertiary alcohols 6e-j exhibit potent cerebral vasodilating activities which are superior to those of cinnarizine and papaverine. Moreover, these compounds show a selective vasodilating effect on vertebral arteries.

  Analogs of 1-[ (3-alkyl-3-hydroxy-3-phenyl) propyl]-4- (2, 3, 4-trimethoxybenzyl) piperazine (1) were prepared and tested for cerebral vasodilating activity. It was found that the potency depends positively on the number of methoxyl groups on the benzyl moiety, and the homopiperazine analogs seem to be equipotent to the corresponding piperazines. From the standpoints of potency and ease of synthesis, 8k was selected for further study. Further analogs, which have various substituents in place of the benzyl moiety of 8k, were prepared and tested for cerebral vasodilating activity. These analogs were less potent than 8k. It was suggested that the benzyl moiety of 8k plays an important role in the high cerebral vasodilating activity.

  1-[ (3-烷基-3-羟基-3-苯基)丙基]-4- (2, 3, 4-三甲氧基苯基)哌嗪（1）的类似物被制备并测试了其脑血管扩张活性。研究发现，活性强度与苄基部分上的甲氧基团数量呈正相关，而同脉哌嗪类的类似物似乎与相应的哌嗪类同样具有活性。从活性和合成简便性来看，选定了8k进行进一步研究。随后制备了在8k的苄基部分替换为各种取代基的其他类似物，并测试了其脑血管扩张活性。这些类似物的活性均低于8k。研究者认为，8k的苄基部分在其高脑血管扩张活性中起着重要作用。
