Versuchsvorschrift
In a manner analogous to that described in Example 1, from 1-methyl-3-(2,6,6-trimethyl-1-cyclohexen-1-yl)allyl-triphenylphosphonium chloride and ethyl 5-formyl-4-methyl-2,4-pentadienoate there is obtained ethyl 4,7-dimethyl-9-(2,6,6-trimethyl-1-cyclohexen-1-yl)-2,4,6,8-nonatetraenoate of melting point 65°-66° C. (from methanol).
