(R)-(-)-1-Cyclohexylethylamine Chemical Properties,Usage,Production

Chemical Properties

optical purity >99% ee

Uses

(R)-(-)-1-Cyclohexylethylamine is used in the preparation of benzylidene(1-cyclohexylethyl)amine by reacting with benzaldehyde. It is also used to prepare chiral polymethacrylamides, which are employed as stationary phases for the liquid-chromatographic resolution of racemic amides. In addition to this, it is used in the preparation of polyamides bound to silica gel for high performance liquid chromatography, which are pressure-stable.

Uses

(R)-(-)-1-Cyclohexylethylamine may be used in the preparation of a chiral calix[4]arene Schiff base derivatives with potential enantioselective recognition ability towards amines.

General Description

(R)-(-)-1-Cyclohexylethylamine is a chiral amine mainly used as a resolving agent for racemic compounds.

Purification Methods

Purify it by conversion to the bitartrate salt (m 172o), then decomposing with strong alkali and extracting into Et2O, drying (KOH), filtering, evaporating and distilling. The hydrochloride salt has m 242o (from EtOH/Et2O), [] D -5.0o (c 10 H2O, from (+) amine). The oxalate salt has m 132o (from H2O). The (±)-base has b 176-178o/760mm, and HCl has m 237-238o.
