N‐Silyl‐Tethered Radical Cyclizations: A New Synthesis of γ‐Amino Alcohols.

Abstract

Amino alcoholsAmino alcohols P 0130 N-Silyl-Tethered Radical Cyclizations: A New Synthesis of γ-Amino Alcohols. -Reaction of N-protected allylamines with the silyl chloride (II) generates bromomethylsilylamines which are subjected to radical cyclization followed by Tamao oxidation. The use of the Boc-protecting group gives the best yield of the corresponding γ-amino alcohol. -(BLASZYKOWSKI, C.; DHIMANE, A.-L.; FENSTERBANK, L.; MALACRIA*, M.; Org.
