Summary

  1. 1.

    Hydrolysis of ethoxyfarnesal acetal (I) yielded ethoxyfarnesal (II), which was converted into ethoxyfarnesenic acid (III) by oxidation.

  2. 2.

    Under the action of boron trifluoride etherate, ethoxyfarnesenic acid underwent cyclization with simultaneous elimination of alcohol to form liquid and crystalline isomers of 4a,5,6,7,8,8a-hexahydro-2,5,5,8a-tetramethylnaphthalenecarboxylic-1 (bicyclodehydrofarnesenic) acid (V).
