| Introduction | 1-(1-naphthyl) ethylamine has two configurations, namely (S)-(-)-1-(1-naphthyl) ethylamine and (R)-1-(1-naphthyl) ethylamine, wherein (S)-(-)-1-(1-naphthyl) ethylamine is an efficient resolving agent for resolving acetylated amino acid derivatives, and (R)-1-(1-naphthyl) ethylamine can not only be used as a resolving agent, but also an important pharmaceutical intermediate. |
| synthesis method | (S)-(-)-1-(1-naphthyl) one of the synthetic methods of ethylamine-biological resolution method: the enzyme, especially Candida antarctica lipase B (CALB) as the catalyst, the use of different chiral 1-(1-naphthyl) the transesterification rate of ethylamine was different, (R)-1-(1-naphthyl) ethylamine was esterified, while (S)-(-)-1-(1-naphthyl) ethylamine was retained, and then the compounds with different chirality were obtained. |
| Use | intermediate of cinacalcet hydrochloride |
