    evaluated in the Lewis acid/organocatalysts-based cooperative catalytic Biginelli reaction, which resulted in the determination of a novel cooperative Lewis acid/primary amine catalyst system, NbCl5/QN-NH2. The synergistic effect of NbCl5 and the quinine-derived primary amine is pronounced and gave dihydropyrimidiones (DHPMs) in moderate to good enantioselectivities (up to 84 % ee) and good to excellent yields

    The present invention provides with a "one pot" easily scalable preparation process, or method to obtain enantiomerically enriched dihydropyrimidinones (DHPMs), in high yield and high enantiomeric purity, based on the concept of organocatalysis by a network of cooperative hydrogen bonds (NCHB). Said preparation process obtains enantiomerically enriched DHPMs without the use of metal-based catalysis and with the possibility of the recovery of the chiral organocatalyst comprising a NCHB used. The present invention also provides with new enantiomerically and diastereomerically enriched hexahydropyrimidinones (HHPMs), as well as a preparation process to obtain them also based on the concept of organocatalysis by a NCHB. Said preparation process obtains enantiomerically and diastereomerically enriched HHPMs without the use of metal-based catalysis and with the possibility of the recovery of the chiral organocatalyst comprising a NCHB used.

    Organocatalysts displaying a network of cooperative hydrogen bonds (NCHB) have been employed in an enzyme‐like manner for a direct, switchable synthesis of enantiopure hexahydropyrimidinones (HHPMs) or dihydropyrimidinones (DHPMs), which starts at a common, easily accessible α‐ureidosulfone stage. The NCHB organocatalyst exploits all its potential as a pure hydrogen‐bond biomimetic catalyst even in
