Gold(I)-Catalyzed Rearrangement Of Alkynylaziridine Indoles For The Synthesis Of Spiro-Tetrahydro-Beta-Carbolines

Functionalized spiro-tetrahydro-β-carbolines were formed by an efficient gold(I)-catalyzed rearrangement reaction of alkynylaziridine indoles. The reaction involved a Friedel–Crafts type intramolecular reaction of alkynylaziridine indoles, following by hydroamination of aminoallene intermediate.
