Porous palladium(II)-polyimines as excellent catalysts for cooperatively catalyzed and enantioselective cascade reactions is disclosed for the first time. In synergy with a chiral amine co-catalyst, polysubstituted cyclopentenes I (R = 4-O2NC6H4, 2-furyl, n-Bu, etc.) and spirocyclic oxindoles II (R = 4-ClC6H4, 4-MeC6H4, n-Pr), including the all-carbon quaternary stereocenter, were synthesized in high yields. High diastereo- and enantioselectivities were achieved for these dynamic kinetic asym. transformations (DYKAT) of enals with propargylic nucleophiles.
