Abstract
Novel synthesis of indene derivatives has been developed in an organocatalytic way. Although homogeneous proline showed low catalytic efficiency, resin-supported proline effectively catalyzed the intramolecular Morita-Baylis-Hillman reaction to afford the desired indenes.
Key words
supported catalysis - annulation - aldehydes - proline - Morita-Baylis-Hillman reaction
