Easy access to (n+3)-dimethylamino-1-ethenylbicyclo[n.1.0]alkanes and their facile conversion to ring-annelated cyclopentadienes

Aminocyclopropanation of 1-ethenylcycloalkenes 2a-d with N,N-dibenzyl- and N,N-dimethylformamide, respectively, by treatment with cyclohexylmagnesium bromide in the presence of methyltitanium triisopropoxide yielded the exo-(n+3)-N,N-dimethylamino-1-ethenylbicyclo[n.1.0]alkanes 3a-d (58-72%). Compounds 7b-d could be transformed by thermal vinylcyclopropane to cyclopentene rearrangement to the corresponding exo-4-dimethylaminobicyclo[n.3.0]alk-1-enes 7b-d (84-90%). Elimination of the dimethylamino group led to the cyclopentadienes 11b-d and 121b-d (72-82%). The 5-dimethylamino-1-ethenylbicyclo[2.1.0]pentane did not undergo the typical vinylcyclopropane rearrangement, but ring-opening at the bridgehead-bridgehead bond to form 1-ethenyl-2-dimethylaminocyclopentene 8.
