実験手順
Using the procedure of Step A of Example 14, (S)α-cyano-3-phenoxy-benzyl (1R, trans) 2,2-dimethyl-3(Z)-[2-fluoro-3-oxo-3-ethoxy-propenyl]-cyclopropane-1-carboxylate was reacted to obtain (S)α-cyano-3-phenoxy-benzyl (1R, trans) 2,2-dimethyl-3(Z)-[2-fluoro-3-oxo-3-hydroxy-propenyl]-cyclopropane-1-carboxylate which was reacted by the process of Step B of Example 14 to obtain (S)α-cyano-3-phenoxy-benzyl (1R, trans) 2,2-dimethyl-3(Z)-[2-fluoro-3-oxo-3-methoxy-propenyl]-cyclopropane-1-carboxylate with a specific rotation of [α]D20 =+15.5°±2.5° (c=0.3% in chloroform).
