Norbornane/ene di‐exo‐condensed isoxazolines were reduced to amino alcohols and then cyclized to 1,3‐oxazines. The phenylimino analogues, 1,3‐oxazin‐2(3H)‐ones, the corresponding 2(3H)‐thiones and 1,4‐oxazepin‐3(4H)‐ones were also prepared. The structures, configurations and conformations of the new compounds were proved via 1H and 13C NMR studies, using DR, DNOE, DEPT and 2D‐HSC measurements in addition
降冰片烷/烯二外缩合异恶唑啉被还原为氨基醇,然后环化为 1,3-恶嗪。还制备了苯基亚氨基类似物、1,3-恶嗪-2(3H)-酮、相应的2(3H)-硫酮和1,4-恶嗪-3(4H)-酮。除了常规光谱外,还使用 DR、DNOE、DEPT 和 2D-HSC 测量,通过 1H 和 13C NMR 研究证明了新化合物的结构、构型和构象。
