Graphical Abstract

Ironed out: An iron-catalyzed asymmetric intramolecular cyclopropanation was realized in high yields and excellent enantioselectivity by using the iron complexes of chiral spiro-bisoxazoline ligands as catalysts. NaBArF=sodium tetrakis[3,5-bis(trifluoromethyl)phenyl]borate.

Abstract

An iron-catalyzed asymmetric intramolecular cyclopropanation was realized in high yields and excellent enantioselectivity (up to 97 % ee) by using the iron complexes of chiral spiro-bisoxazoline ligands as catalysts. The superiority of iron catalysts exhibited in this reaction demonstrated the potential abilities of this sustainable metal in asymmetric carbenoid transformation reactions.
