Twenty -substituted pyrrolo[3,4-]quinoline-1,3-diones were synthesized by a cyclization reaction of Pfitzinger's quinoline ester precursor with the selected aromatic, heteroaromatic and aliphaticamines. The structures of all derivatives were confirmed by IR, H NMR, C NMR and HRMS spectra, while their purity was determined using HPLC techniques. Almost all compounds were identified as a new class ofpotent

cyclization cascade reaction of Pfitzinger's ester and benzoyl hydrazines has been developed providing a simple procedure for synthesis of pyrrolo [3,4-c]quinoline-1,3-dione derivatives. Unlike traditional synthetic protocol, this method avoids an additional step of conversion of quinoline-3,4-dicarboxylic acids to an anhydride, allowing direct reaction of ester derivative with hydrazine nucleophiles.
已开发出一种有效的 pTSA 介导的 Pfitzinger 酯和苯甲酰肼的环化级联反应,为合成吡咯并 [3,4- c ] 喹啉-1,3-二酮衍生物提供了一种简单的方法。与传统的合成方案不同,该方法避免了将喹啉-3,4-二羧酸转化为酸酐的额外步骤,允许酯衍生物与肼亲核试剂直接反应。
