Procedure
By proceeding in a similar manner to that hereinbefore described in Example 3(iii), but replacing the 6-(7-trimethylsiloxyheptyl)-7-(3-oxooct-1-enyl)-1,4-dioxaspiro[4,4]nonane used as starting material by the appropriate quantity of 6-(7-trimethylsiloxyheptyl)-7-(3-oxo-4-phenoxybut-1-enyl)-1,4-dioxaspiro[4,4]nonane, there was prepared 7-(3-hydroxy-3-methyl-4-phenoxybut-1-enyl)-6-(7-trimethylsiloxyheptyl-1,4-dioxaspiro[4,4]nonane.
