Abstract
A new class of alpha-aromatic-N-hydroxylamines has been prepared by reaction of tert-butyl (phenylsulfonyl)alkyl-N-hydroxycarbamates with aromatic and heteroaromatic Grignard reagents. Reactions proceed via a base-assisted elimination of the phenylsulfonyl group leading to N-Boc nitrones. This methodology has been applied to the synthesis of zileuton.
