실험 절차

Microbial cells (IFO-1575; Zygoascus hellenicus) were cultured in an MY medium (pH 6.0; 50 ml) at 30° C. for 48 hours. Methyl 2-(2,3,4-trifluoroanilino)propionate (1.0 g) was suspended in a 0.1 M phosphate buffer solution (pH 6.5; 90 ml). Then the above-described liquid culture (10 ml) was added thereto and gently stirred. The mixture was stirred for additional 16 hours while maintaining at 30° C. Then it was treated as in Example 43 to thereby give methyl (2R)-2-(2,3,4-trifluoroanilino)propionate (0.39 g, optical purity 91% ee) and the title compound (0.45 g, optical purity 84% ee).
