## Abstract The stereochemistry of benzannelated 1,6βdiazabicyclo[4.2.1]octaβ3,7βdienes (the conformation of the eightβmembered ring and of the variable substituents on the methylene bridge) was determined by means of NOE enhancements and stereospecific longβrange H,H coupling constants in the rele
The cyano and carbonyl groups are strongly electron withdrawing (-I). However. in recent years considerable experimental and theoretical efforts have been made in evaluating the ITconjugative electron donation (+M) of these substituents toward cationic carbon (schemes 1 and 2).' As for the effect of
