chloroacetyl chloride in the presence of N,N-dimethylacetamide resulted in the formation of the mesoion imidazo[1,2-a]pyridinium-3-olate instead of the reported 4-oxopyrimidinium-5-olate. We performed some functionalizations and present two single crystal X-ray analyses.
在N,N-二甲基乙酰胺的存在下2-苯胺基吡啶与氯乙酰氯的反应导致形成了中羟咪唑并[1,2 - a ]吡啶-3-油酸酯,而不是所报道的4-氧嘧啶鎓-5-油酸酯。我们进行了一些功能化,并提出了两个单晶X射线分析。
