Eight new γ-(N-arylsulfonyl)aminopropyl silatranes are synthesized by substitution of γ-(N-substituted) aminopropylsilatranes or γ-aminopropylsilatranes. with arylsulfonyl chlorides. The structures of these compounds are identified with IR, 1H NMR,MS and elemental analysis. Their antibacterial activities are also carrled out, and all the title compounds are found to be active against staphylococcus aureus. The compounds showing the highest activity are those ...
