A new protocol for multicomponent condensation reactions that uses fluorous (highly fluorinated) substrates is introduced. This method takes advantage of the ease of purification of fluorouscompounds by liquid-liquid extractions between fluorous and organic solvents. The application of this method to the Ugi and Biginelli reactions is described. The condensation products of these two reactions, amino
