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.

stabilised carbon nucleophiles. The few reports of organometallic additions have limited scope of substrate and organometallic nucleophile. We report a novel, one-pot methodology that functionalises N-substituted tetrahydroisoquinolines by visible light-assisted photooxidation, followed by trapping of the resultant iminium ions with organometallic nucleophiles. This affords 1,2-disubstituted tetrahydroisoquinolines
