  摘要：

  A series of isothiazolopyrimidines and isoxazolopyrimidines were synthesized and identified as potent KDR inhibitors. SAR studies led to isothiazolopyrimidine urea analogs that potently inhibit VEGFR tyrosine kinases (KDR enzymatic and cellular IC50 values below 10 nM) as well as cKIT and TIE2. The selected compounds 8 and 13 display 56% and 48% oral bioavailability in mice, respectively. (c) 2006 Elsevier Ltd. All rights reserved.

  摘要：

  糠醛和 5-硝基糠醛与羟胺、N-甲基羟胺和 O-甲基羟胺反应的脱水步骤的速率常数与 pH 值的关系图显示了对应于氧鎓离子催化和自发脱水的两个区域。糠醛与上述羟胺反应的氧鎓离子催化脱水区域表现出具有优异布朗斯台德相关性的一般酸催化（布朗斯台德系数：0.76 (r = 0.986)、0.68 (r = 0.987) 和 0.67 (r = 0.993)）分别）。然而，这些羟胺的自发脱水的速率常数（其中水被认为是一般酸催化剂）与布朗斯台德线有很大的正偏差。其他作者在非羟基胺与不同芳香醛的反应中没有观察到这一事实，因此支持这些反应的自发脱水步骤是通过分子内催化进行的。分子内催化的机理可能是逐步的。首先，形成两性离子中间体。然后它可以在第二步中通过失水进化，或遵循协调的途径，质子通过五元环转移（一般分子内酸催化）。在非羟基胺的情况下，数据表明分子内质子通过一个或两个水分子从胺的氮转移到离开的氢氧根离子的机制的可能性。©

  2-chloro-1-methylpyridinium iodide is an efficient and mild reagent for the dehydration of aldoximes to nitriles under mild conditions. In continuation of our interest in developing mild method for the conversion of aldoximes to nitriles, we herein wish to report the first application of DEPC to the efficient synthesis of nitriles from aldoximes under mild conditions (Scheme 1).

  腈是有机合成中有价值的中间体，不仅因为它们是各种官能团的合适前体，而且因为它们被广泛用作药物、农用化学品和各种 N-杂环化合物的关键中间体。氰基本身也经常存在于许多重要的生物学分子中。因此，已经开发了多种从不同化学前体合成腈的路线。在这些路线中，使用合适的脱水剂从醛肟合成腈是一种通用且清洁的方法。为此，使用了许多试剂，例如氯磺酰异氰酸酯、二-2-吡啶基亚硫酸盐、Burgess 试剂、[RuCl2(对甲基异丙基苯)]2/MS 4A、4d BOP、Pd(OAc)2/PPh3、4f Cu(OAc) 2/超声4g已研制成功。然而，这些试剂 可能在某些方面存在局限性，例如苛刻的反应条件、使用昂贵或不易获得的试剂、产率低和缺乏通用性。因此，仍然需要开发用于这种转换的温和且通用的方法。磷氰酸二乙酯 (DEPC) 最初是作为一种有效的肽偶联剂引入的，并已被用于有用的有机反应。以前，我们报道了 2-chlo
