All of the nitrogen-bridged polycyclic derivatives of 1 and 3 containing a number of centers of asymmetry were formed with nearly complete diastereoselectivity. Considerable differences were observed in the ring-closing abilities of the unsubstituted and phenyl-substituted aminonaphthols 1 and 2 and of the regioisomeric compounds 1 and 3.
