Abstract

The synthesis of 22 2-aryl-1H-indoles, including 12 new compounds, has been achieved via Pd-or Rh-mediated methodologies, or selective electrophilic substitution. All three methods were based on elaborations from simple indole precursors. SAR studies on these indoles and 2-phenyl-1H-indole in Staphylococcus aureus as NorA efflux pump inhibitors indicated 5-nitro-2-(3-methoxycarbonyl) phenyl-1H-indole was a slightly more potent inhibitor than ...
