Published: August 2013

An enantioselective intramolecular indole aminohydroxylation reaction is catalyzed by iron(II)-chiral bisoxazoline (BOX) complexes (ee up to 99%, dr > 20:1). This discovery enables expedient asymmetric synthesis of a series of biologically active 3-amino oxindoles and 3-amino indolanes.
