  Synthesis of the new pseudo-symmetrical tamoxifen derivatives and their anti-tumor activity

  摘要：

  Three new pseudo-symmetrical tamoxifen derivatives, RID-B (15), C (16), and D (17), were synthesized via the novel three-component coupling reaction, and the structure-activity relationships of the pseudo-symmetrical tamoxifen derivatives were examined. It was discovered that 15 strongly inhibits the viability of HL-60 human acute promyelocytic leukemia, whereas 16 possesses medium activity against the cell line and 17 has no effect on the cell viability. The agarose gel electrophoresis for DNA cleavage showed the cell death might be induced by apoptosis. (C) 2007 Elsevier Ltd. All rights reserved.

  The synthesis of N-alkyl-1H-1,2,4-triazoles from N,N-dialkylhydrazones and nitriles via formal [3+2] cycloaddition including the C-chlorination/nucleophilic addition/cyclisation/dealkylation sequence was developed. This sequential reaction utilising the in situ generation of hydrazonoyl chloride based on the ambiphilic reactivity of hydrazones afforded a variety of multi-substituted N-alkyl-triazoles

  日期：2020.6.5

  allylic alcohols to 1,5-dienes in the presence of B2pin2 with excellent regioselectivity has been developed. Mechanistic studies indicate that the reaction proceeds via sequential nickel-catalyzed borylation of allyl alcohols followed by cross-coupling of the resulting allyl boronates with allyl alcohols. The method was effectively applied to nickel-catalyzed allylation of aldehydes using allylic alcohols

  已经开发了在B 2 pin 2存在下具有极好的区域选择性的镍催化的烯丙基醇与1，5-二烯的均和交叉偶联。机理研究表明，该反应是通过依次进行的镍催化的烯丙醇的硼化反应，然后将所得的硼酸烯丙酯与烯丙醇交叉偶联而进行的。该方法有效地应用于直接使用烯丙醇的镍催化醛的烯丙基化反应。
• Accessing Difluoromethylated and Trifluoromethylated <i>cis</i> ‐Cycloalkanes and Saturated Heterocycles: Preferential Hydrogen Addition to the Substitution Sites for Dearomatization
  作者：Xue Zhang、Liang Ling、Meiming Luo、Xiaoming Zeng

  DOI：10.1002/anie.201907457

  日期：2019.11.18

  Reported here is a straightforward process in which a cyclic (alkyl)(amino)carbene/Rh catalyst system facilitates the preferential addition of hydrogen to the substitution sites of difluoromethylated and trifluoromethylated arenes and heteroarenes, leading to dearomative reduction. This strategy enables the diastereoselective synthesis of cis-difluoromethylated and cis-trifluoromethylated cycloalkanes

  此处报道的是一种简单的方法，其中环状（烷基）（氨基）卡宾/ Rh催化剂体系有助于将氢优先添加到二氟甲基化和三氟甲基化的芳烃和杂芳烃的取代位上，从而导致脱芳族还原反应。该策略使非对映选择性合成顺式-二氟甲基化和顺式-三氟甲基化的环烷烃和饱和的杂环，甚至允许形成具有定义的赤道取向的二-和三氟甲基的全顺式多-三氟甲基化的环状产物。氘标记研究表明，氢优先攻击平面芳烃的取代位，从而导致脱芳香化作用，可能以异质Rh为反应性物种，

  selective aldol reaction mediated by boron compounds and a mild organic base (DBU) was developed. Inclusion of electron-withdrawing groups in the amino acid derivative ligands reacted with BH3·SMe2 forms a boron promoter with increased Lewis acidity at the boron atom and facilitated the carboxylic acid selective enolate formation, even in the presence of other carbonyl groups such as amides, esters, ketones
