ABSTRACT
Chiral single-point binding ruthenium Lewis acid catalysts [Ru(acetone)((S,S)-BIPHOP-F)(Cp)][SbF6] ((S,S)-1a) and [Ru(acetone)((S,S)-BIPHOP-F)(indenyl)][SbF6] ((S,S)-1b) efficiently catalyze intramolecular Diels-Alder (IMDA) reactions of trienals under mild conditions to afford the endo cycloaddition products as the major products in good yields with high diastereo- and enantioselectivities.
