amino/imino equilibrium. In the 2‐amino‐2‐oxazoline form the endo nitrogen is more reactive than the exo one. In the imino‐2‐oxazolidine form, the contrary occurs. Depending on the experimental conditions, substitutive reactions take place either on the endo or on the exo nitrogen. The crystal structures of two endo/exo N‐substituted compounds were determined by X‐ray crystallography.
五元杂环的脒基诱导互变异构的氨基/亚氨基平衡。在 2-氨基-2-恶唑啉形式中,内氮比外氮更具反应性。在亚氨基-2-恶唑烷形式中,情况正好相反。根据实验条件,取代反应发生在内部或外部氮上。通过 X 射线晶体学确定了两种内/外 N 取代化合物的晶体结构。
