(R)-(+)-1-(1-Naphthyl)ethylamine Usage And Synthesis

Chemical Properties	Colorless to light yellow liqui
Uses	(R)-(+)-1-(1-Naphthyl)ethylamine is used in chiral synthesis in organic reactions including the synthesis of β-amino acids and the enantioselective of ketones to nitroolefins.
Uses	It is used in chiral synthesis in organic reactions including the synthesis of β-amino acids and the enantioselective of ketones to nitroolefins. Also used as absolute configuration of primary amines determined using chiral (2-nitrophenyl)proline amides and H NMR.
General Description	(R)-(+)-1-(1-Naphthyl)ethylamine is a chiral derivatization reagent useful for all gas chromatography (GC) applications in the chiral field. It is specially selected to meet the requirements for derivatization reagents for enantiomeric excess determinations.
Purification Methods	Purify the amine by distillation in a good vacuum. [Mori et al. Tetrahedron 37 1343 1981, cf Wilson in Topics Stereochem (Allinger and Eliel eds) v o l 6 135 1971, Fredga et al. Acta Chem Scand 11 1609 1957.] The hydrochlorides crystallise from H2O [] D 18 ±3.9o (c 3, H2O), and the sulfates recrystallise from H2O as tetrahydrates m 230-232o. The RS-amine has b 153o/11mm, 156o/15mm, 183.5o/41mm [Blicke & Maxwell J Am Chem Soc 6 1 1780 1939]. [Beilstein 12 III 3111.]
