Description	Facile methods for direct ethoxycarbonylation and carbamoylation reactions on some cyclic ketones is described and discussed. A principle of this solution is an application of ultrasonic solid-liquid phase-transfer-catalysis for an enolate anion generation. Enolate anion reacts further with electrophilic reagents, i. e. with ethyl chlorocarbonate in the case of ethoxycarbonylation or nitrourea for carbamoylation reaction.
