Reactions of some alpha,beta-unsaturated ketones from terpenoid series with CH-acids in the presence of Cs-beta zeolite were studied under various conditions. The variation of reaction conditions (heating, ultrasonic irradiation) strongly affected the reaction products ratio, and the effect was singular in each case and gave different results.
