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.
