study of dynamic nitroaldol systems aided the discovery of a diastereoselective crystallization process through amplification of 2-nitro-1-(pyridine-4-yl)propan-1-ol. The phenomenon was further developed into an effective procedure for asymmetic synthesis of pyridine-nitroalcohols and several substrates were screened to this end. These results demonstrate how work with larger dynamic systems facilitates
动态硝基醛醇系统的研究有助于通过放大 2-nitro-1-(pyridine-4-yl)propan-1-ol 发现非对映选择性结晶过程。该现象进一步发展成为吡啶-硝基醇不对称合成的有效程序,为此筛选了几种底物。这些结果证明了使用更大的动态系统如何促进和增加偶然发现的可能性。
