Description

Application

(S)-(-)-2′-Amino-1,1′-binaphthalen-2-ol or (S)-NOBIN, is a non-symmetrically substituted 1,1′-binaphthalene ligand. It can be used as a catalyst in the asymmetric synthesis of unnatural α-alkyl amino acids by phase-transfer catalysis (PTC). (S)-NOBIN can also be employed as starting material to prepare N-monoalkyl and N,N-dialkyl (S)-NOBIN analogs by reacting with aldehydes via reductive amination reaction. N-monoaryl derivatives are obtained from NOBIN via Hartwig−Buchwald arylation reaction.

Packaging
