A diaminomethyleneindenedione motif can serve as an excellent double hydrogen bonding donor. Bifunctional chiral primary amine 3 bearing a diaminomethyleneindenedione motif is an excellent organocatalyst to promote the asymmetric conjugate additions of va

Calix[4]arene based chiral bifunctional thiourea-primary amines have been shown to act as effective catalysts for the Michael addition of aldehydes to maleimides for the first time. The corresponding adducts were generally obtained preferentially in (R)-

Fluorous thiourea organocatalyst 3 promotes the Michael reaction of aldehydes with maleimides to afford the corresponding adducts in high yields with up to 99% ee. Fluorous organocatalyst 3 can be easily recovered as an insoluble precipitate from the reac
