In situ preparation of a multifunctional chiral hybrid organic-inorganic catalyst for asymmetric multicomponent reactions

García García, Pilar; Zagdoun, Alexandre; Coperet, Christophe; Lesage, Anne; Díaz Morales, Urbano Manuel; Corma Canós, Avelino (Royal Society of Chemistry, 2013)

[EN] A chiral mesoporous organosilica material incorporating a urea based-cinchona derivative and propylamine groups was prepared by a co-condensation method. The multisite solid catalyst efficiently promoted the asymmetric ...
Organic-inorganic supramolecular solid catalyst boosts organic reactions in water

García García, Pilar; Moreno Rodríguez, José María; Díaz Morales, Urbano Manuel; Bruix, Marta; Corma Canós, Avelino (Nature Publishing Group, 2016-02)

[EN] Coordination polymers and metal-organic frameworks are appealing as synthetic hosts for mediating chemical reactions. Here we report the preparation of a mesoscopic metal-organic structure based on single-layer assembly ...
Regio-, Diastereo-, and Enantioselective Organocatalytic Addition of 4-Substituted Pyrazolones to Isatin-Dereved Nitroalkenes

Vila, C.; Dharmaraj, N. R.; Faubel, A.; Blay, G.; Cardona, M. L.; Muñoz Roca, María Del Carmen; Pedro, J. R. (John Wiley & Sons, 2019-05-26)

[EN] Hydroquinine 2,5-diphenyl-4,6-pyrimidinediyl diether [(DHQ)(2)Pyr] catalyzed the regio-, diastereo-, and enantioselective addition of 4-substituted pyrazolones to isatin-derived nitroalkenes, providing a variety of ...
