on the aromatic nucleus is outlined. These compounds were required for the preparation of aza-analogs of the anti-inflammatory oxindole tenidap. Two methods of synthesis were used, the first involving the addition of malonate to 2-chloro-3-nitropyridine derivatives followed by nitro group reduction and one-pot cyclization/hydrolysis/decarboxylation. The second method, utilizing the vicarious nucleophilic
概述了在芳香核上带有取代基的一组八个氮杂吲哚的制备。这些化合物是制备抗炎性羟吲哚替尼达的氮杂类似物所需要的。使用了两种合成方法,第一种包括向2-氯-3-硝基吡啶衍生物中添加丙二酸酯,然后进行硝基还原和一锅环化/水解/脱羧。第二种方法是利用硝基吡啶衍生物的替代性亲核取代(VNS)反应(随后进行硝基还原和一锅环化/水解),构成了一条新的途径来制造氮杂吲哚。
