METHOD OF THE SYNTHESIS OF SELENIUM HOMOLOG OF RUCAPARIB

Abstract
We have developed a practical protocol from readily available 5-fluoro-2-hydroxybenzoic acid to access a selenium homolog of rucaparib. The crucial step is Lewis acid mediated 5-endo-dig cyclization of ethynyl aniline with the following intramolecular electrophilic selenylation leading to the one-pot construction of a tricyclic system.
