Abstract:Optically pure N-Benzyl-1-phenylethylamine have been prepared from optically active α-phenylethylamine and benzaldehyde via hydrogenation of the intermediate N-Benzylidene-1-phenylethylamine by KBH_4 . The specific rotation of R-(+)-N-Benzyl-1-phenylethylamine is +38.28°and that of S-(-)-N-Benzyl-1-phenylethylamine is -39.75°.The yield is about 85%. |
Key words:N-benzyl-1-phenylethylamine; α-phenylethylamine; benzaldehyde; KBH_4 |
