The 'H and "C NMR spectra of cis-and trans-fused N-methyloctahydro-2H-1,3-and -3,l-benzoxazines and their 2-methyl derivatives were analysed. All trans-fused derivatives studied existed in biased double chair conformations with roughly equal contributions of the equatorial and axial N-methyl groups.

## Abstract The ^1^H and ^13^C NMR spectra of 4,8,9,10‐tetraaryl‐1,3‐diazatricyclo[3.3.1.13, 7]decan‐6‐ones were measured at 400 and 500 and at 100 and 125 MHz, respectively. The chemical shifts were assigned unambiguously using one‐ and two‐dimensional (H,H‐COSY, C,H‐COSY, NOESY, ROESY and HMBC) N
