A new series of fluoroquinolone‐based benzothiazolyl‐4‐thiazolidinone hybrids has been yielded via sulfated tungstate‐promoted highly accelerated N‐formylation at a piperazine residue of ciprofloxacin and norfloxacin entities. The formylated fluoroquinolone moieties were then coupled with substituted 2‐aminobenzothiazoles, which were generated from their respective para‐substituted amines to form...
Step economical, multicomponent construction of two series based on quinoline and coumarin ring systems was carried out. Annulation towards the 2‐piperazinylthiazole system was established in satisfactory yields, using copper(II) triflate. These multicomponent reaction products were examined for their potential inhibitory effect against two Gram‐positive bacteria (Staphylococcus aureus and Bacillus cereus...
