TL;DR: In this article, a polystyrene-supported N-sulfonyl-(Ra)-binam-D-prolinamide catalyst was used for the direct aldol reaction between different ketones and aldehydes.

TL;DR: Wet unsupported and supported 1,1'-binaphthalene-2,2'-diamine (BINAM) derived prolinamides are efficient organocatalysts under solvent-free conditions at room temperature to perform the synthesis of chiral tacrine analogues in good yields and excellent enantioselectivies (up to 96%).

TL;DR: In this article, the authors used a silica-gel supported binam-derived prolinamides for the intramolecular and intermolecular aldol reaction under solvent-free conditions using conventional magnetic stirring.

TL;DR: (S(a))-Binam-D-prolinamide is an efficient organocatalyst for the direct aldol reaction between α-keto esters as electrophiles and alkyl and α-functionalised ketones, under quasi solvent-free conditions, providing access to highly functionalised chiral quaternary α-hydroxyesters with up to 92% ee.

TL;DR: In this paper, a bottom-up strategy was used for the synthesis of cross-linked copolymers containing the organocatalyst N-{(1R)-2′-{[(4-ethylphenyl)sulfonyl]amino}[1,1′-binaphthalen]-2-yl}-D-prolinamide derived from 2 (Scheme 1).
