  名称：

  Alkali-metal mediated zincation of N-heterocyclic substrates using the lithium zincate complex, (THF)Li(TMP)Zn(tBu)2 and applications in in situ cross coupling reactions

  摘要：

  This study investigates the ability of the mixed-metal reagent [Li(TMP)Zn(tBu)(2)] 1 to promote direct Zn-H exchange reactions (zincations) of a wide range of N-heterocyclic molecules. The generated metallated intermediates from these reactions are intercepted with I-2 and some of them are also employed as precursors in Pd-catalysed Negishi cross-coupling applications. A comparison with recent precedents in metallation chemistry reveals that for some of these heterocycles, 1 allows improved conversions, under milder conditions and in certain cases, even gives unique regioselectivities.

  Disclosed are a nitrogenous heterocyclic compound, intermediates, a preparation method, a composition and use thereof. The nitrogenous heterocyclic compound in the present invention is as shown in formula I. The compound has a high inhibitory activity towards ErbB2 tyrosine kinase and a relatively good inhibitory activity towards human breast cancer BT-474 and human gastric cancer cell NCI-N87 which express ErbB2 at a high level, and at the same time has a relatively weak inhibitory activity towards EGFR kinase. Namely, the compound is a highly selective small-molecule inhibitor targeted at ErbB2, and hence it has a high degree of safety, and can effectively enlarge the safety window in the process of taking the drug.

  本公开揭示了一种含氮杂环化合物、中间体、制备方法、组合物及其用途。本发明中的含氮杂环化合物如公式I所示。该化合物对ErbB2酪氨酸激酶具有较高的抑制活性，并且对人类乳腺癌BT-474和人类胃癌细胞NCI-N87表达ErbB2的抑制活性相对较好，同时对EGFR激酶具有相对较弱的抑制活性。换句话说，该化合物是一种高度选择性的针对ErbB2的小分子抑制剂，因此具有很高的安全度，并且可以有效地扩大服药过程中的安全窗口。
