the one hand, different types of unknown lactam systems with and without a rearrangement under ring contraction of the benzothiazine substructure were selectively obtained. In this investigation, annulated lactams without ring contraction were formed by oxidation of the sulfide group to a sulfone group in the benzothiazine skeleton. On the other hand, benzothiazoles, which are oxidation products, were
基于亚胺 1,4-苯并噻嗪的甲氧基酰胺的转化根据取代模式产生了三种不同的产品。一方面,选择性地获得了不同类型的未知内酰胺体系,在苯并噻嗪亚结构的环收缩下有和没有重排。在这项研究中,没有环收缩的环状内酰胺是通过将硫化物基团氧化成苯并噻嗪骨架中的砜基团而形成的。另一方面,分离出氧化产物苯并噻唑。所有类型内酰胺的结构均通过 X 射线衍射验证。
