## Abstract The ^1^H and ^13^C NMR spectra of 26 2,3‐dihydro‐[1,5]benzoxazepin‐4(5__H__)‐one derivatives and four thiono analogues are interpreted in terms of conformational equilibria. Similar to 1,3,4,5‐tetrahydro‐2__H__‐1,5‐benzodiazepin‐2‐ones, these compounds favour boat conformations of the s
