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). (C) 2013 Elsevier Ltd. All rights reserved.
Catalyst-Controlled Selectivity in C−S Bond Formation: Highly Efficient Synthesis of C2- and C3-Sulfonylindoles
Exploring a potential catalyst system for catalyst‐controlled selectivity in C−Sbondformation is a fascinating challenge. Herein, we described two novel and highlyefficient methods for the selectivesynthesis of C2‐ and C3‐sulfonylindoles showing good biological activities by employing iodide and copper catalysts, respectively. Mechanistic studies point to the crucial role of the electronic properties
