Abstract

N, N'-Diisopropylferrocenecarboxamide is utilized for a directed metalation using n- butyllithium-(-)-sparteine to access planar chiral bifunctional aminoboronate ferrocene derivatives after amide reduction, providing (p R)-2-[(N, N-diisopropylamino) methyl] ferrocenylboronic acid and derivatives with high enantiomeric excess.
