A transition-metal-free protocol for the one-pot synthesis of 2-benzyl/2-allyl-substituted thiobenzoazoles in water was developed. The cyclization of 2-aminothiophenols, 2-aminophenols, and 1,2-phenylenediamines with tetramethylthiuram disulfide (TMTD) gave mercapto benzoheterocycles, and the subsequent C-S coupling with benzyl or allyl halides furnished the desired products in good to excellent yields. This method features transition-metal-free conditions with water as a solvent, an easy performance, mild reaction conditions, a wide substrate scope, and good to excellent yields, thus paving an efficient and useful way to establish a library of potentially active drug molecules.
Preparation and in vitro evaluation of benzylsulfanyl benzoxazole derivatives as potential antituberculosis agents
exhibited significant activity against both sensitive and resistant strains of M. tuberculosis and also against non-tuberculous mycobacteria. To facilitate drug design of benzoxazole as potentialantituberculosisagent, we have explored the quantitative structure–activity relationship (QSAR). We demonstrated that lower lipophilicity has significant contribution to activity. Dinitrobenzylsulfanyl derivative

were designed and synthesised as Pseudomonas aeruginosa (P. aeruginosa) quorumsensing inhibitors in this paper. We experimentally demonstrated that 6b significantly inhibited the formation of P. aeruginosa PAO1 biofilm without affecting the growth. Further mechanistic studies showed that 6b affected the luminescence of quorumsensing reported strain PAO1-lasB-gfp and the production of P. aeruginosa PAO1
