The synthesis based on palladium catalytic coupling of 38 new-arylated benzo[b]thiophenes or thiophenes is described in a few steps. We also report the direct arylation of the position 3 of the benzo[b]thiophenic structure, a 'one pot' 2,5-heterodiarylation of thiophenes as well as the synthesis of precursors of amino-acids with a 2-arylated benzo[b]thiophene core. These compounds were evaluated on bacteria strains: most of them did not exhibit any antibiotic activity but were found to selectively inhibit the NorA multidrug transporter of Staphylococcus aureus. As such, they restored the activity of the NorA substrates ciprofloxacin against a resistant S. aureus strain in which this efflux pump is over-expressed.
