New N-Alkyl-nitroindazolylacetonitriles were efficiently obtained via vicarious nucleophilic substitution of N-methyl-nitroindazoles with 4-chlorophenoxyacetonitrile. All compounds were fully characterized by NMR and mass spectroscopy techniques and the structures of some of them were additionally confirmed by X-ray diffraction analysis data. Tautomeric switching was observed in this series of nitroindazolylacetonitriles upon addition of basic anions followed by UV-Vis spectrophotometric and 1H-NMR titrations. The formation of tautomeric species induced by anionic species was endorsed by Density Functional Theory calculations.

Several novel 2-alkylamino- and 2-alkylthiothiazolo[5,4-e]- and -[4,5-g]indazoles and their 6-alkyl and 8-alkyl derivatives have been synthesised in high overall yields starting from 5-nitro and 6-nitroindazoles in a three-step route involving the regioselective cyclisation of thioureidoindazoles and indazolyl dithiocarbamates as the key steps. Some assorted thiazoloindazoles have been screened for anticancer properties, which demonstrated the anticancer potential of at least one product, justifying its further follow-up.
