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
Ken-ichi Yamada et al.
The Journal of organic chemistry, 77(3), 1547-1553 (2012-01-03)
Triethylborane-mediated tin-free radical alkylation of N-alkoxycarbonyl-imines, such as N-Boc-, N-Cbz-, and N-Teoc-imines, proceeded smoothly at a low temperature (-78 to -20 °C) to give the corresponding adducts in high yield. Although the formation of isocyanate was the major unfavorable reaction
