The first proline-catalyzed Friedlander annulation for the synthesis of 2-substituted 4-trifluoromethyl quinoline derivatives is described. Excellent re gio selectivity as well as good yields were shown in a variety of cases, and a tandem aldol-cyclization pathway might be involved. ((c) Wiley-VCH Verlag GmbH & Co.
