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

A metal‐free synthesis of 2‐benzyl/allyl‐substituted thiobenzoazoles was developed starting from tetramethyl thiuram monosulfide (TMTM) which served as thiocarbonyl surrogate. By using 2‐aminophenols (or 2‐aminothiophenols, or 1,2‐phenylenediamines) and TMTM as starting materials, 2‐mercaptobenzoazoles could be synthesized efficiently, and the subsequent C–S bond formation with allyl/benzyl halides
Longchained and SO3H‐functionalized ionic liquids derived from pyrrolidine were employed as metal‐free, efficient and recyclable catalyst for thiolation of alcohols with several kinds of thiols, providing up to 99 % yield within 0.25 h at room temperature.

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
