generated in situ from indeno quinoxaline and thiazolidine-2-carboxylic acid to a series of quinoline bearing dipolarophile afforded novel spiro indeno-quinoxaline pyrrolo thiazoles in quantitative yields. The newly synthesized compounds were characterized using different spectroscopic techniques. Furthermore, the molecular structure of compound 5c was confirmed by single crystalX-ray crystallography
A facile regio- and stereoselective synthesis of novel spiro[indolin-3,2′-pyrrolidin]-2-one’s <i>via</i> 1,3-dipolar cycloaddition of azomethine ylides
ABSTRACT A facile regio and stereoselectivesynthesis of novel spiro[indolin-3,2′-pyrrolidin]-2-one’s have been accomplished through 1,3-dipolarcycloaddition of azomethine ylides generated in situ from the reaction of isatin and benzyl amine with quinoline bearing dipolarophiles in good yields. The synthesized compounds were well characterized through different spectroscopic techniques, such as single

elemental analysis. The synthesized compounds were screened for in vitro antioxidant activity using DPPH, nitric oxide, super oxide radical and in vitro cytotoxic activity against MCF-7 and A-549 cancer cell lines and visualized using the fluorescent microscopic technique. The newly synthesized compounds exhibited excellent antioxidant activity compared to the standard molecule, i.e., BHT. In terms of cytotoxic
