The present invention relates to methods for the preparation of solid-supported heterogeneous organic catalyst covalently bound to textile materials, preferably via photochemical immobilization. More specifically, the present invention relates to the organocatalysis and recognition process by using the textile-supported chiral molecules.

An intriguing effect of electronegative 2,6-substituents on the stereochemical outcome of (S) -proline-catalyzed aldol reactions between benzaldehyde derivatives and acetone is reported. Remarkably high enantioselectivities can be achieved with such substrates.
