摘要

We have studied the conversion of substituted norbornadienes into a substituted 2- azabicyclo [3.2. 1] octadiene system via reaction with toluenesulfonyl azide. We have found that both and mono-and disubstituted norbornadienes will undergo the cycloaddition/ rearrangement sequence to provide the bicyclooctadiene ring system as a single regioisomer. The 2-azabicyclo [3.2. 1] octane ring system can be prepared from the ...
