Alkylative amination of aldehydes was achieved via a carbon-carbon bondformation by the intermolecular alkyl radical addition to the carbon-nitrogen doublebond of oxime ethers generated in situ from aldehydes and benzyloxyamine. Alkyl radical addition to oxime ethers via a route involving the iodine atom-transfer process was found to be largely dependent on the reaction temperature and eliminated
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.
