Abstract Acetic acid functionalized poly(4-vinylpyridinium) bromide (APVPB), as a new and heterogeneous catalyst, was designed and successfully tested on the synthesis of 2-aminospiro[indoline-3,4ʹpyran]-2-one and spiro[indeno[1,2-b]quinoxaline-11,4-pyran]-2ʹ-amine derivatives. Also, infrared spectroscopy (FT-IR), thermal gravimetric analysis (TGA), differential thermal gravimetric (DTG), scanning
摘要 醋酸功能化聚(4-乙烯基吡啶)溴化物(APVPB)作为一种新型的非均相催化剂,设计并成功用于合成2-氨基螺[indoline-3,4ʹpyran]-2-one和螺[indeno[ 1,2-b]quinoxaline-11,4-pyran]-2ʹ-胺衍生物。此外,红外光谱(FT-IR)、热重分析(TGA)、差热重重(DTG)、扫描电子显微镜(SEM)、X射线衍射分析(XRD)和能量色散X射线分析(EDX)该催化剂已在所提出的工作中进行了研究。将制备的螺吡喃溶解在DMSO中,通过DPPH自由基清除试验和对尖孢镰刀菌的抗真菌活性进行抗氧化活性筛选。结果表明,合成的螺吡喃具有很强的抗氧化活性(IC50;0.161 ± 0.009 to 1. 509 ± 0.007 mg/ml)和对尖孢镰刀菌的良好抑制活性(在 500 ppm 浓度下为 65.8 ± 1.4% 至 88.3 ± 2.2%,在 1000
