Description

General description

(R)-(+)-2′-Amino-1,1′-binaphthalen-2-ol is a non-symmetrically substituted 1,1′-binaphthalene ligand.

Application

(R)-(+)-2′-Amino-1,1′-binaphthalen-2-ol may be used as a catalyst in the asymmetric PTC (phase-transfer catalysis) synthesis of α-amino acids. (R)-NOBIN reacts with trans-azobenzene-4,4′-dicarbonyl chloride to form poly(ester-amide)s, which shows backbone light-regulated chiroptical response.

Packaging
