  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.

  本发明基于协同氢键网络（NCHB）有机催化的概念，提供了一种 "一锅式 "易扩展的制备工艺或方法，以高产率和高对映体纯度获得对映体富集的二氢嘧啶酮（DHPMs）。所述制备工艺无需使用金属催化，即可获得对映体富集的 DHPM，并有可能回收由所使用的 NCHB 组成的手性有机催化剂。本发明还提供了新的对映异构体和非对映异构体富集的六氢嘧啶酮（HHPMs），以及同样基于 NCHB 有机催化概念的获得它们的制备工艺。该制备工艺无需使用金属催化即可获得对映体和非对映异构体富集的六氢嘧啶酮（HHPMs），并有可能回收由所使用的 NCHB 组成的手性有机催化剂。
