catalytic Ugi-type condensation of α-isocyanoacetamide and chiral cyclic imine is developed, where the combination of phenyl phosphilic acid and trifluoroethanol is exploited to promote the Ugi-type condensation with α-isocyanoacetamide for the first time. Under this new catalytic system, the reaction using the cyclic imines as relatively inertial substrates proceed well, and chiral 3-oxazolyl-mor
Several novel heterocycles have been constructed asymmetrically on the basis of a catalyticUgi-type condensation of α-isocyanoacetamide and chiral cyclic imine. The combination of phenylphosphilic acid and trifluoroethanol is exploited to promote an Ugi-typereaction with α-isocyanoacetamide for the first time. By means of this reaction, chiral 3-oxazolyl morpholin-2-one/piperazin-2-one derivatives
