Summary: A one-pot condensation reaction of 1H-indazol-6-amine, isatin, and barbituric acid or 2-thiobarbituric acid in refluxing ethanol, in the presence of L-proline, efficiently synthesizes novel spiro[indoline-3,11'-pyrazolo[3,4-f]pyrimido[4,5-b]quinoline] derivatives. This method offers simplicity in operation, high product yield, and straightforward experimental and work-up procedures. The structures of all synthesized compounds were confirmed using IR, H-1 NMR, C-13 NMR, F-19 NMR, and HRMS analysis.

Summary: A highly stereo-selective, one-pot, multicomponent method was used to synthesize novel functionalized 1,3-cycloaddition spirooxindoles (SOXs) (4a-4h). The synthesized SOXs were analyzed for drug-likeness, ADME parameters, and anticancer activity. Molecular docking analysis revealed that SOX 4a had substantial binding affinity with CD-44, EGFR, AKR1D1, and HER-2, and functional studies showed that SOX 4a induced cell death in cancer cells by affecting cytoplasmic and nuclear architecture and inducing ROS generation.

Summary: A convenient method for constructing novel dispirooxindole motifs was developed through a base-promoted three-component reaction of ammonium acetate, isatins, and in situ-generated 3-isatyl-1,4-dicarbonyl compounds. The reaction of dimedone adducts of 3-ethoxy-carbonylmethyleneoxindoles with ammonium acetate and isatins, promoted by pi-peridine, produced multifunctionalized dispiro[indoline-3,2'-quinoline-3',3-indoline] derivatives with good yields and high diastereoselectivity. A similar reaction of dimedone adducts of 3-phenacylideneoxindoles yielded unique dispiro[indoline-3,2'-pyrrole-3',3-indoline] derivatives with a cyclohexanedione substituent. A plausible reaction mechanism is proposed to explain the formation of the different spirooxindoles.

Summary: A straightforward and environmentally friendly method using a photocatalyst eosin y and a 22 W LED lamp in ethanol was developed for producing spiro[indoline-3,4'-quinoline]. This method involves the oxidative coupling of indole with enaminone and malononitrile. Key features of this method include metal-free synthesis, low cost, environmental friendliness, non-toxicity, ease of handling, and utilization of renewable energy like visible light. This method demonstrates a wide substrate scope for indole and active methylene compounds, including different enaminones, enabling the production of spiro compounds under benign reaction conditions for the first time.

Summary: In this study, an eco-friendly method for synthesizing pyrimido[4,5-b]quinolones and indenopyrido[2,3-d]pyrirnidines was introduced. The synthesis was carried out via a three-component coupling reaction under solvent-free conditions using Fe3O4@nano-cellulose/Sb(V) as a catalyst. The catalyst could be separated by an external magnet and reused for subsequent reactions.

Summary: A sulfonated poly-4-vinyl pyridinium (PVPy-IL-B-SO3H) catalyst was prepared and used for the three-component reaction of malononitrile with 1-alkylindoline-2,3-diones and 1,3-dimethylpyrimidine-2,4,6(1H,3H,5H)-trione or methyl 5-hydroxy-1H-pyrazole-3-carboxylate. Under ultrasonic irradiation conditions, the reaction yielded methyl 6'-amino-5'-cyano-2-oxo-2'H-spiro[indoline-3,4'-pyrano[2,3-c]pyrazole]-3'-carboxylates or -3,4'-pyrano[2,3-d]pyrimidine]-6'-carbonitrile derivatives. The solid catalyst offered easy separation, low cost, high yields, and eliminated the need for column chromatography in product isolation and purification.

Summary: In this research, two novel nano-size inorganic-bioorganic hybrids based on graphene oxide were prepared. The bio-based ionic liquids obtained through the reaction of arginine and malonic acid were characterized. These bio-based ionic liquids were then embedded on graphene oxide core to form the final nano-size inorganic-bioorganic hybrids. The catalytic efficacy of the obtained nanostructures in the synthesis of various compounds was examined, and it was found that one of the nanostructures exhibited faster catalytic reactions than the other. The recovery and reusability of the nanostructure with higher catalytic efficacy were successfully demonstrated.
