Stereocontrol in solid-phase radical reactions: radical addition to oxime ether anchored to polymer support
A high degree of stereocontrol in solid-phase radical reactions was achieved by using triethylborane and diethylzinc as a radical initiator at low reaction temperature. Alkyl radical addition to Oppolzer's camphorsultam derivatives of oxime ether anchored to polymer support proceeded smoothly to give the alpha-amino acid derivatives with excellent diastereoselectivities.
