摘要

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 ...
