摘要

The diastereoselective alkyl radical addition to chiral oxime ethers was studied with a view to preparing enantiomerically pure α,β-dialkyl-β-amino acid derivatives. The phase transfer-catalyzed alkylation of Oppolzer's camphorsultam derivative of oxime ether proceeded smoothly to give the alkylated N-(β-oximino)acyl derivatives. In the presence of BF3·OEt2, radical addition to the oxime ethers proceeded using triethylborane as the radical initiator to give α,β-dialkyl-β-amino acid derivatives with excellent diastereoselectivity.
