Procedure
4-Methyl-8-vinyl-4,8-nonadienal was used in place of 4-methyl-8-vinyl-4,7-nonadienal in the reaction described in Example 1 d). for preparing α-sinensal. The resulting aldehyde, β-sinensal, was obtained in comparable yields and had the same constants as the product obtained according to Example 4 d).
