Versuchsvorschrift
By replacing in the above Example 2,6,6-trimethyl-1-[1,3-dioxo-but-1-yl]-cyclohex-2-ene by 2,6,6-trimethyl-1-[1,3-dioxo-but-1-yl]-cyclohex-1-ene the corresponding test samples have an analogous organoleptic note. Similar, but less pronounced effects, were obtained by the use of 2,6,6-trimethyl-1-[3-hydroxy-butan-1-oyl] -cyclohex-2-ene or 2,6,6-trimethyl-1-[3-hydroxy-butan-1-oyl]-cyclohex-1-ene.
