Used in organic synthesis as a key intermediate for the preparation of complex molecules, particularly in the development of pharmaceuticals and agrochemicals. Its structure, featuring both indole and dioxaspiro components, makes it valuable for constructing compounds with potential biological activity. It is often employed in the synthesis of alkaloids and other heterocyclic compounds that may exhibit therapeutic properties. Additionally, its reactive sites allow for further functionalization, enabling researchers to tailor its properties for specific applications in drug discovery and material science.
