Asymmetric Friedel-Crafts Alkylation of Indoles Catalyzed by Chiral Aziridine-Phosphines
Over the course of the present studies, a series of optically pure phosphines functionalized by chiral aziridines was synthesized in reasonable/good chemical yields. Their catalytic activity was checked in the enantioselective Friedel-Crafts alkylation of indoles by beta-nitrostyrene in the presence of a copper(I) trifluoromethanesulfonate benzene complex. The corresponding Friedel-Crafts products were achieved efficiently in terms of chemical yield and enantioselectivity (up to 85% in some cases).
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 6224-63-1 help many people in the next few years. Recommanded Product: Tri-m-tolylphosphine.
