FeCl3-Catalyzed Oxidative Allylation of sp2 and sp3 C−H Bond Adjacent to a Nitrogen Atom: Easy Access to Homoallyl Tertiary Amines
摘要:
Oxidative allylation to sp(2)- and sp(3)-carbon attached to the nitrogen atom was accomplished. The alpha-allylation of tertiary amines was catalyzed by easily available hydrated iron(III) chloride in combination with air or aqueous (BuOOH)-Bu-t. Remarkably, N-allyl- and N-propagyl-tethered tertiary amines were also allylated through this protocol.

The reaction of arynes and secondary allylamines furnished ortho-allyl-substituted N-arylanilines via an aza-Claisen rearrangement. In this transformation, the sequential formation of C–C and C–N bonds occurred by involving two aryne molecules under metal-free reaction conditions to provide moderate to good yields of the products. The obtained ortho-allyl-substituted N-arylaniline derivatives were
