Application

  • Indole is a nitrogen-containing heterocycle used in the total synthesis of compounds such as goniomitine, (−)-isatisine A, and (±)-aspidospermidine.
  • It is used as an electron donor moiety in synthesizing dyes for organic photovoltaics.
  • It can also be used in the preparation of indole based conjugated small molecules for nonlinear optics applications.
