Abstract
The recycling resolution of(RS)-1-(1-naphthyl)ethylamine[(RS)-1] and(RS)-1-(2-naphthyl)ethylamine[(RS)-2] was studied in this paper.(R)-1-(1-naphthyl)ethylamine(31% yield,98%ee) and(R)-1-(2-naphthyl)ethylamine(30% yield,98%ee) were obtained via resolution of the racemic(RS)-1 and(RS)-2 by using D-tartaric acid as a resoluting agent.Meanwhile racemization of the non-target enantiomeric isomers from mother liquor was performed,and the recycling resolution was realized.
