Chiral Vicinal Diamines for Asymmetric Synthesis

Chiral vicinal diamines are of tremendous interest to the synthetic chemist as they are found in many chiral catalysts and pharmaceuticals.

The Chin group is interested in computational and experimental approaches to understanding stereoselective recognition and catalysis. Their studies in weak forces (H-bonding, electronic and steric effects) has led to a highly efficient method for making limitless varieties of chiral vicinal diamines from the 'mother diamine' that are useful for developing stereoselective organocatalysts or transition metal-based catalysts as well as for developing drugs (Acc Chem Res (2012) p1345). The 'mother diamine' is also useful for making binol, monophos and binap analogs. The Chin group is also interested in using reversible covalent bonds for stereoselective recognition and L to D conversion of natural and non-natural amino acids (EJOC (2012) p229).

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
