Synthesis and antimicrobial activity of some 5-aryl-2-[N,N-disubstituted thiocarbamoylthio)acylamino]-1,3,4-oxadiazoles.

In this study, a number of novel 5-aryl-2-[(N,N-disubstituted thiocarbamoylthio)acylamino]-1,3,4-oxadiazole derivatives were synthesized by the reaction of potassium salts of N,N-disubstituted dithiocarbamoic acids with 2-[(alpha-chloro-alpha-phenylacetyl/alpha-bromopropionyl)-amino]-5 -aryl-1, 3,4-oxadiazoles. Structures of the compounds were confirmed by the spectral data (IR, 1H NMR, EIMS) and elemental analyses. Most of the compounds were tested against various microorganisms and four of them were found to be weakly active against Staphylococcus aureus and Staphylococcus epidermidis.
