  摘要：

  吡唑并[3,4-d]嘧啶是嘌呤的吡唑并类似物。它们已被证明是一类具有A1腺苷受体亲和力的化合物。已经合成了两个系列的1-甲基异鸟苷的吡唑并[3，4-d]嘧啶类似物。第一个涉及N1位置的取代，而第二个涉及N5位置的取代。检查了烷基和芳基取代基。通过使用（R）-[3H] -N6-（苯基异丙基）腺苷结合测定法测试所有化合物的A1腺苷受体亲和力。3-氯苯基在N1位上显示最大活性，而丁基在N5位上显示最大活性。在这些位置的每一个中最好的取代基的组合增强了整体活性。最有效的化合物是4-氨基-5-N-丁基-1-（3-氯苯基）-1H-吡唑并[3,4-d]嘧啶-6（5H）-，IC50为6.4 x 10（- 6）M.通过用[3H] CGS 21680进行A2腺苷受体亲和力测定，检查了在受体亚类上的选择性。这一系列化合物对A2受体的效力稍弱。4-氨基-5-N-丁基-1-（3-氯苯基-1H-吡唑并[3,4-d]嘧

  The reductive single electron transfer (SET) umpolung amination of aldehyde-derived hydrazones has been developed through visible-light-promoted photoredox catalysis. The ideal transformation of hydrazones into the corresponding hydrazonamide through selective carbon–hydrogen (C–H) bond functionalization represents one of the most step- and atom-economical methods. This SET umpolung strategy features

  作者：Signe Korsager、Dennis U. Nielsen、Rolf H. Taaning、Troels Skrydstrup

  DOI：10.1002/anie.201304072

  日期：2013.9.9

  New tricks for an old dog: The Pd‐catalyzed carbonylative α‐arylation of monoethyl potassium malonates with aryl bromides and reactive aryl chlorides provides a simple and direct route to aryl β‐ketoesters. Because only stoichiometric amounts of carbon monoxide are employed, the method is ideal for the introduction of carbon isotopes into more complex structures.
