反応手順
Using the procedure of Step F of Example 9, (1R,cis) 2,2-dimethyl-3-[(Z) 3-oxo-3-(2,2-difluoroethoxy)-1-propenyl]-cyclopropane-carboxylic acid and (R)α-cyano-3-phenoxy-benzyl alcohol were reacted to obtain (R)α-cyano-3-phenoxy-benzyl (1R,cis) 2,2-dimethyl-3-[(Z) 3-oxo-3-(2,2-difluoroethoxy)-1-propenyl]-cyclopropane-carboxylate with a specific rotation of [α]D20 =+117.5°±3° (c=0.6% in chloroform).
