Procedure
Using the procedure of Example 9, (1R, cis, ΔZ) 2,2-dimethyl-3-(3-sec-butoxy-3-oxo-1-propenyl)-cyclopropane-carboxylic acid and (3-propyn-2-yl-2,5-dioxo-imidazolidinyl)-methanol were reacted to obtain (3-propyn-2-yl-2,5-dioxo-imidazolidinyl)-methyl (1R, cis, ΔZ) 2,2-dimethyl-3-(3-sec-butoxy-3-oxo-1-propenyl)-cyclopropane-carboxylate with a specific rotation of [α]D20 =+16.5°±1° (c=0.8% in chloroform).
