Synthesis of polyfunctionalized benzophenones via the reaction of 3-formylchromones with tertiary push-pull enamines

Uncatalyzed nucleophilic reaction of 3-formylchromones with tertiary push-pull enamines in refluxing acetonitrile gave polyfunctionalized benzophenone derivatives as a result of a [3+3] annulation in moderate to good yields.

Synthesis of 1-(2-hydroxy-phenyl)-3-piperidin-1-yl-propenone by ultrasonic irradiation

Different 1-(2-hydroxy-phenyl)-3-piperidin-1-yl-propenones have been synthesized by ultrasonic activation from differently substituted 3-formyl chromones and piperidine. Copyright Taylor & Francis Group, LLC.
