Although poly (ionic liquids) (PILs) have attracted great research interest owing to their various applications, the performance of nanoporous PILs has been rarely developed in the catalysis field. To this end, a micro-mesoporous PIL with acid-base bifunc
Synthesis, partition coefficients and antibacterial activity of 3′-phenyl (substituted)-6′-aryl-2′(1H)-cis-3′,3′ a -dihydrospiro[3-H-indole-3,5′-pyrazolo (3′,4′-d)-thiazolo-2- (1H)-ones]

The reaction of indole-2,3-dione (1a) and/or 1-methylindole-2,3-dione (1b) with mercaptoacetic acid in the presence of 4-toluenesulfonic acid as a catalyst afforded spirooxathialane>-2,5'-diones (2a, b).Compounds 2a and/or 2 b were reacted with the appropriate aliphatic and/or aromatic primary amines to give compounds 3a-j.The reaction of 2a, b with hydrazine hydrate, phenylhydrazine and p-nitrophenylhydrazine yielded spiroderivatives 4a-c.Friedel-Crafts reactions of 2a and 2b with arenes in the presence of aluminium chloride catalyst afforded spiroindoline isothiochroman derivatives 5a-h.Key words: Spiroindoline derivatives; spiroheterocycles; NMR.
