Enantioselective Friedel-Crafts reactions between phenols and N-tosylaldimines catalyzed by a leucine-derived bifunctional catalyst

Enantioselective Friedel-Crafts reactions between phenols and N-tosylaldimines were developed using a bifunctional catalyst readily prepared from l-leucine. The chiral benzylic amine products were obtained in high yields (up to 96% yield) and good to high enantiomeric excesses (up to 95% ee).

Chiral primary amine mediated conjugate addition of branched aldehydes to vinyl sulfone: Asymmetric generation of quaternary carbon centers

Novel l-threonine-derived bifunctional organic catalysts containing primary amine and sulfonamide groups were utilized to promote asymmetric conjugate addition of α,α-disubstitued aldehydes to 1,1-bis(benzenesulfonyl) ethylene. The adducts with quaternary
