The stereochemistry of benzannelated 1,6‐diazabicyclo[4.2.1]octa‐3,7‐dienes (the conformation of the eight‐membered ring and of the variable substituents on the methylene bridge) was determined by means of NOE enhancements and stereospecific long‐range H,H coupling constants in the relevant NMR spectra.
