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.

A series of tetrahydropyrimidine derivatives (2a - 2l) were designed, synthesized, and screened for anti-HIV-1 properties based on the structures of HIV-1 gp41 binding site inhibitors, NB-2 and NB-64. A computational study was performed to predict the pharmacodynamics, pharmacokinetics, and drug-likeness features of the studied molecules. Docking studies revealed that the carboxylic acid group in the

Biginelli, hydrolysis and Ugi four component reaction sequence was developed for the synthesis of novel dihydropyrimidinone (DHPM) bisamides in which an unprecedented but moderate 1,6 asymmetric induction was observed for this compound class. A detailed study is carried out to understand effects of various substitutions on the diastereoselectivity. Steric congestion led to sluggish Mumm rearrangement in some
