tripodalpiperidin-4-ones was carried out by the reaction of 4-piperidonehydrochloride monohydrate with different alkylating and acylating agents. It was preferably reduced to respective piperidin-4-ols by ultrasonic irradiation using silica chloride, which maintains higher yields by acting as an effective supporting polymer. The sterically hindered phthaloyl derivative of piperidin-4-one was synthesized by ultrasonic
