| Hazard Information | Back Directory | [Description]
(S)-(-)-1-(1-Naphthyl)ethylamine(10420-89-0) is an organic compound used as a raw material for organic synthesis. Chiral moieties were connected to the heteroatom-bridged calix-triazin scaffold by reactions of (S)- or (R)-(+)-1-(1-Naphthyl)ethylamine with tetraazacalix[4]arene[2]triazine.
| [Chemical Properties]
Colorless to light yellow liqui | [Uses]
(S)-(-)-1-(1-Naphthyl)ethylamine(10420-89-0) is used in the asymmetric synthesis of α-cyanocarboxylates. Also used in the synthesis of chiral imadazolin-2-ylidene ligands used in organometallic catalysis. Chiral/
Asymmetric synthesis.
| [Uses]
(S)-(-)-1-(1-Naphthyl)ethylamine(10420-89-0) is used in the asymmetric synthesis of α-cyanocarboxylates. Also used in the synthesis of chiral imadazolin-2-ylidene ligands used in organometallic catalysis. Chiral/Asymmetric synthesis.
| [Synthesis]
Using enzymes, particularly Candida Antarctic Lipase B, as catalysts, and utilizing the different transesterification rates of 1-(1-naphthyl)ethylamines of different chiralities, (R)-1-(1-naphthyl)ethylamine is esterified, while (S)-(-)-1-(1-naphthyl)ethylamine is retained. And then (S)-(-)-1-(1-naphthyl)ethylamine can be obtained by separation .
| [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.] |
