Procedure

(E)-N-Cinnamoyl-2-fluorobenzamide (26.9 mg, 0.1 mmol), malononitrile (13.2 mg, 0.2 mmol) and the compound (10 mol %) shown in the following Table 2 as an asymmetric catalyst were stirred in toluene (1.0 mL) at room temperature for 27 hr. The reaction mixture was purified by silica gel column chromatography (n-hexane/ethyl acetate=4/1) to give the title compound as a white solid.
