    金催化有机金属的氧化联芳基交叉偶联
    摘要:
    联芳基亲核试剂之间的偶联(AR δ-:arylboronates或芳基硅烷)和亲电(AR δ+:芳基卤化物)代表了碳-碳键形成的最新技术。这些反应中固有的官能团限制源于钯和镍催化剂对卤素,硼酸酯和碱敏感取代基的高催化反应性。在这里,我们报告了一般的二聚体金催化的芳基硼酸酯和芳基硅烷的氧化交叉偶联反应,而没有用于合成的外部碱,具有不对称联芳基的优异的官能团耐受性。两种偶合剂均易于获得,稳定且无毒。各种各样的(假)卤代和硼化偶合剂可以成功地应用于这种位点特定的联芳基偶合剂,具有前所未有的多功能性。简明地制备几种π共轭有机材料和药效基团已证实了其合成价值。

  • Structure–activity study leading to identification of a highly active thienopyrimidine based EGFR inhibitor
    作者:Steffen Bugge、Svein Jacob Kaspersen、Synne Larsen、Unni Nonstad、Geir Bjørkøy、Eirik Sundby、Bård Helge Hoff
    DOI:10.1016/j.ejmech.2014.01.042
    日期:2014.3
    Based on the thieno[2,3-d]pyrimidine scaffold, a series of new 4-amino-6-aryl thienopyrimidines have been prepared and evaluated as EGFR tyrosine kinase inhibitors. The in vitro activity was found to depend strongly on the substitution pattern in the 6-aryl ring, the stereochemistry, and the basicity at the secondary 4-amino group. A stepwise optimization by combination of active fragments led to the discovery of three structures with EGFR IC50 < 1 nM. The most potent drug candidate had an IC50 of 0.3 nM towards EGFR and its mutants L858R and L861Q. Studies using human cancer cell lines and an EGFR-L858R reporter cell system revealed good cellular potency, verifying the identified thienopyrimidines as promising lead structures.

  • Palladium-Catalyzed Phosphine-Free Direct C–H Arylation of Benzothiophenes and Benzofurans Involving MIDA Boronates
    作者:Mengmeng Huang、Yangjie Wu、Zhiwei Wang、Yabo Li、Beiqi Yan
    DOI:10.1055/s-0034-1379606
    日期:——
    With high regioselectivity, a series of benzoheterocyclic compounds were synthesized via palladiium-catalyzed phosphine-free C-H arylation of benzothiophenes/benzofurans with aryl MIDA boronates at 30-50 degrees C in moderate to excellent yields. MIDA boronates were used in C-H arylation of heterocycles for the first time. Under the optimal conditions, the benzothiophenes could be transformed into the beta-arylbenzothiophenes, and the benzofurans gave only alpha-aryl-substituted products.
