Abstract

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(3__H__)‐ones, the corresponding 2(3__H__)‐thiones and 1,4‐oxazepin‐3(4__H__)‐ones were also prepared. The structures, configurations and conformations of the new compounds were proved via ^1^H and ^13^C NMR studies, using DR, DNOE, DEPT and 2D‐HSC measurements in addition to the routine spectra.
