An efficient one-pot synthesis of N-aryl[3,4-d]pyrazolopyrimidines in good yield and under mild reaction conditions is described. By exploiting electron-deficient hydroxylamines, the substituted oxime products were formed with very high E-diastereoselectivity. The key step utilizes a cyclization reaction upon an oxime derived from hydroxylamine-O-sulfonicacid to form the N–N bond of the product.
描述了N-芳基[3,4- d ] 吡唑并嘧啶的高效一锅法合成,收率良好,反应条件温和。通过利用缺电子羟胺,形成了具有非常高的E-非对映选择性的取代肟产物。关键步骤是利用羟胺-O-磺酸衍生的肟进行环化反应,形成产物的 N-N 键。

A series of [1-aryl-1H-pyrazolo[3,4-d]pyrimidin-4-yl]arylhydrazones were discovered as novel inhibitors glycogen synthase kinase-3 (GSK-3). Based on initial modeling a detailed SAR was constructed. Modification of the interior binding aryl ring (Art) determined this to be a tight binding region with little room for modification. As predicted from the model, a large variety of modifications could be incorporated into the hydrazone aryl ring. This work led to GSK-3 inhibitors in the low nano-molar range. (C) 2004 Elsevier Ltd.
