The reaction of sodium cyclopentadiene of lithium indene with tosylamino tosylates of amino alcohols yield a series of novel N-alkylcyclopentadiene sulfonamides. These cyclopentadiene derivatives are potential ligands capable of chelating to transition metals. Optically active derivatives were prepared starting from chiral β-amino alcohols.
