    Project supported by the National Natural Science Foundation of China (Nos. 20606030, 20936002), the National High-tech Research and Development Program of China (No. 2011AA02A209) and the Major State Basic Research Development Program of China (Nos. 2011CB710800, 2009CB724706).

Enantiomerically pure (R)-1-(2-naphthyl)ethylamine was firstly prepared by an efficient enzymatic kinetic resolution process. The effects of lipases, solvents, acyl donors, substrate concentration and temperature on the reaction were investigated. It was found that as the acyl donor, 4-chlorophenyl valerate could effectively inhibit the non-selective amidation reaction. The optimal solvent, amine concentration and temperature were toluene, 300 mmol/L and 40 ℃, respectively. Under the optimal conditions mentioned above, an excellent eep value (>99%) at high conversion (50%) in 8 h could be achieved on the kinetic resolution reaction catalyzed by Novozym 435 with the new acyl donor.

Key words: (R)-1-(2-naphthyl) ethylamine, 4-chlorophenyl valerate, Novozym 435, enzymatic kinetic resolution
