(R)-(+)-1,1-BI-2-NAPHTHOL DIMETHYL ETHER - Uses and synthesis methods
introduction
Since the two enantiomers of (R)-( )-2, 2-dimethoxy -1, 1-binaphthalene are C2 symmetric bodies containing 2 identical binaphthalene rings, its rigid structure and C2 symmetry play an important role in chiral induction. It is an excellent chiral ligand and chiral auxiliary reagent, it is one of the most common structures in chiral synthesis, especially chiral catalysis.
Preparation
Using 1-bromo-2-methoxynaphthalene and 2-methoxynaphthalene-1-boric acid as starting materials, prepare the target compound (R)-( )-2, 2-dimethoxy-1, 1-binaphthalene
