摘要：

In this manuscript we described the FeCl3/diorganyl diselenides promoted intramolecular cyclization of o-alkynyl anilines, as an alternative for the construction of functionalized 3-organoselenyl indoles. The cyclization reactions proceeded smoothly at room temperature in the presence of air giving the 3-organoselenyl indoles in good yields. Additionally, the 3-organoselenyl indoles proved to be quite useful as synthetic intermediates for the construction of more functionalized indole units through a selenium-lithium exchange reaction followed by trapping the lithium intermediate with different electrophiles.
