Stereocontrol in radical reactions of oxime ether anchored to polymer support was studied. Highly diastereoselective solid-phase radical reaction was achieved by using triethylborane and diethylzinc as a radical initiator at low reaction temperature, providing a novel method for the synthesis

The aqueous medium radical reactions of a variety of imine derivatives such as oxime ether, oxime, hydrazone, nitrone, and N-sulfonylimine were investigated. Triethylborane-mediated intermolecular alkyl radical addition to glyoxylic oxime ether, oxime, and nitrone in water proceeded smoothly to give
