General description

5-Iodoindole can be synthesized via nitration of m-toluidine.

Application

5-Iodoindole (5-iodogramine) may be used in the synthesis of the following:
  • 3-dimethylaminomethyl-5-iodoindole via reaction with dimethyl amine and formaldehyde
  • 5-ethynyl-1H-indole obtained via refluxing with trimethylsilylacetylene in the presence of triethylamine, catalyzed by palladium and copper(I)iodide in acetonitrile
  • 5-(3-hydroxyprop-1-enyl)-1H-indole via reaction with allyl alcohol in the presence of triphenyl phosphine, palladium acetate and silver acetate in dimethylformamide
  • 5-(3-benzyloxyprop-1-enyl)-1H-indole via reaction with allylbenzyl ether in the presence of triphenyl phosphine, palladium acetate and silver acetate in dimethylformamide
  • 5-(2-phenylethynyl)-1H-indole via refluxing with phenylacetylene catalyzed by copper(I)iodide and palladium in the presence of triethylamine in acetonitrile

Multi-drug resistance in nematodes is a serious problem as lately several resistant phenotypes have emerged following the intermittent usage of synthetic nematicides. Contemporary research continues to focus on developing and/or repurposing small molecule inhibitors that are eco-friendly. Here, we describe
