Preclinical ResearchA series pf novel (7 S , 11 R )—substituted diphenyl‐2,4,8,10‐tetraazaspiro [5.5] undecane‐3‐thio‐1,5,9‐triones 4 a‐j and (7 S ,11 R )‐substituted diphenyl‐2,4,8,10‐tetraazaspiro[5.5] undecane‐3‐thio‐1,5 dione, 9‐thiones 5 a‐j were prepared using substituted aldehydes and urea/thiourea in the presence of thiobarbituric acid under solvent free, thermal and microwave conditions catalyzed by ecofriendly K ‐10 clay. The antibacterial potency of these compounds in vitro on the gram negative strains E scherichia coli and P seudomonas aeruginosa and gram positive strains S taphyllococcus aureus and S taphylococcus epidermidis was evaluated.
