Sažetak
Amino acid substituted monodentate triphenylphosphine ligands Lig-Aa1-Aa2-Aa3-Z 5 and 6, with a C-terminal ester or amide group, respectively, were prepared in a few simple synthetic steps. Supramolecular in situ formed complexes [Rh(COD)(Lig-Aa1-Aa2-Aa3-Z)2]BF4 3 and 4 with a prochiral coordination sphere of the metal are selective hydrogenation catalysts (up to 68% ee). The selectivity is induced by transmission of chirality via distant hydrogen-bonded amino acids with a Herrick-like secondary structure ("backdoor induction").
