ZnO-mediated regioselective C-arylsulfonylation of indoles: a facile solvent-free synthesis of 2- and 3-sulfonylindoles and preliminary evaluation of their activity against drug-resistant mutant HIV-1 reverse transcriptases (RTs)

A ZnO-mediated one-pot solvent-free protocol for the regioselective C-arylsulfonylation of indoles is described and some novel derivatives were tested on wild type and non-nucleoside inhibitor resistant K103N and Y181C HIV-1 reverse transcriptases (RTs).
