highly efficacious synthetic route has been developed for the synthesis of spiro[indoline-3,9′-xanthene]trione and spiro[chromene-4,3′-indoline]-3-carbonitrile derivatives using graphene oxide-supported dicationic ionicliquid (DIL@GO) as a heterogeneous catalyst in aqueous media. Targeted spiro[indoline-3,9′-xanthene]trione derivatives were synthesized via one-pot condensation of substituted isatins

nanocatalyst was evaluated in the synthesis of spirooxindole derivatives. Also, the use of ultrasonication further demonstrated the versatility of this protocol in addition to other features like simple work-up procedure, mild reaction conditions, simple catalyst recovery, short reaction time and the use of environmental friendly solvents. In vitro biological evaluation of the synthesized compounds also revealed
在这项研究中,使用 FT-IR、p-XRD、SEM、EDS、TEM、TGA 和 VSM 等不同技术制备并表征了一种磁性可回收多相催化剂 Fe 3 O 4 @PPCA。在螺氧吲哚衍生物的合成中评估了纳米催化剂的催化效率。此外,除了简单的后处理程序、温和的反应条件、简单的催化剂回收、较短的反应时间和使用环保溶剂等其他功能外,超声波的使用进一步证明了该协议的多功能性。合成化合物的体外生物学评价还揭示了化合物4ce的抗结核活性,而化合物4ga、4gb和4gc显示出深远的抗氧化活性。还使用密度泛函理论 (DFT) 对有机转化的机理途径进行了计算研究,以确定 PPCA 的催化作用。
