The first example of intermolecular carbon radicaladdition to unactivated aldoxime ethers in the presence of BF3·OEt2 has provided a new efficient carboncarbon bond-forming method for the synthesis of a variety of amines.
Intermolecular carbon radical addition to the carbon-nitrogen double bond of oximeethers and hydrazones was studied. The reaction of unactivated aldoxime ethers proceeded smoothly in the presence of BF3·OEt2 to give the alkylated products in high yields via the free radical-mediated carbon-carbon bond-forming process.
