Abstract
PURPOSE: To obtain the title compound for use as a preparation of perfume at a low price in high yields, by reacting hept-1-ene-4-ine compound or 4-heptyne compound with an organic acid, followed by hydrolyzing.
CONSTITUTION: Hept-1-ene-4-ine compound [e.g.; 6-(4'-methyl-3'-cyclohexene-1'- yl)-hept-1-ene-4-ine-6-ol, etc.] shown by the formula I (R1 is H or alkyl; R2 is acyl) or 4-heptyne compound [e.g.; 6-(4'-methyl-3'-cyclohexene-1-yl)-4-heptyne- 2,6-diol, etc.] shown by the formula II (R3 and R4 are H or acyl) is reacted with a lower carboxylic acid (e.g., organic acid such as acetic acid) in the presence of a heavy metal catalyst, e.g., cupric acetate, etc., in an organic inert solvent at 50W110°C. The resulting intermediate (IX, X, XI, XII) is hydrolyzed in the presence of KOH, etc to give the title compound shown by the formula III.
