実験手順

Using the procedure of Example 84, 2.1 g of (R, S) cyano-2-(6-phenoxy-pyridyl)-methyl (1R, cis, ΔZ) 2,2-dimethyl-3-(3-hydroxy-3-oxo-1-propenyl)-cyclopropane-carboxylate and 1 ml of cyclobutanol were reacted and the oil residue was chromatographed over silica gel. Elution with an 8-1 cyclohexane-ethyl acetate mixture yielded 1.6 g of (R, S) cyano-2-(6-phenoxy-pyridyl)-methyl (1R, cis, ΔZ) 2,2-dimethyl-3-(3-cyclobutoxy-3-oxo-1-propenyl)-cyclopropane-carboxylate with a specific rotation of [α]D20 =+44.5°±2° (c=0.5% in benzene).
