derivatives are reported and are shown to have the expected different tautomeric arrangements. The unusual features of the NH-tautomer (3e) were interpreted in terms of the RAHB (resonance-assisted hydrogen bond) model and its relative stability was investigated by ab initio and DFT calculations.
通过新的温和的还原程序,使用含有柔性N-CH-CH基团的叔胺,通过新的温和的还原程序制备了芳基甲基
异恶唑-5-酮(3)。并发工艺与还原竞争,产生了相当数量的链延伸产物(4)。报告了两种选择的芳基甲基衍
生物的X射线结构,并显示具有预期的不同互变异构排列。用RAHB(共振辅助氢键)模型解释了NH-互变异构体(3e)的不寻常特征,并通过从头算和DFT计算研究了其相对稳定性。
