Three new chiral monoanionic ON ancillary phenolate ligands with varying pendant arms have been synthesized in moderate to high yields 50% - 85% via Mannich-type condensation reaction of chiral substituted phenol, formaldehyde and +-bis-R-1-phenylethylamine. These new organic compounds were fully characterized via nuclear magnetic resonance spectroscopy 1H and 13C and elemental analysis. The newly synthesized ligands are suitable candidates for metal-catalyzed ring-opening of lactones and asymmetric catalysis.
