Trost ligand

The Trost ligand or Trost's ligand is a ligand designed by Barry Trost working at Stanford University. It is used in coordination complexes to generate catalysts that are employed in asymmetric synthesis.

The (S,S)-DACH-naphthyl Trost ligand is (1S,2S)-(-)-1,2-diaminocyclohexane- N,N'-bis(2-diphenylphosphino- 1-naphthoyl) is a modification of the ligand using naphthalene as the arene group in place of phenyl.

It is part of a larger groupe of ligands derived from 1,2-diaminocyclohexane (DACH).
