It was shown that the synthetic isomers of citral, obtained from the monoadducts of the chlorotelomer of isoprene, only form E-enones during alkaline condensation with acetone.Under the influence of mineral acids the (3E, 5Z)- and (3E, 5E)-6,10-dimethyl-3,5,9-undecatrien-2-ones formed from the Z and E isomers of citral gave a mixture of α-, β-, and γ-ionones, hydroxyionone, and 10-hydroxypseudoionones.The isomeric (3E, 5Z)-(3E, 5E)6,8,8-trimethyl-3,5,9-decatrien-2-ones and (3E, 5E)-5,10-dimethyl-3,5,9-undecatrien-2-one, obtained from the skeletal isomers of citral, do not undergo cyclization under the indicated conditions.The isolated compounds were characterized by (13)C NMR spectroscopy.
