Gd. Artman et al., Preparation of N-sulfonylimines bearing easily removable protecting groupsvia the Hudson reaction of oximes with sulfinyl chlorides, SYNLETT, (2), 2001, pp. 232-233
N-Sulfonylimines which incorporate easily cleavable t-butylsulfonyl (Bus),
and beta -trimethylsilylethanesulfonyl (SES) groups on nitrogen can be read
ily synthesized from oximes and the corresponding sulfinyl chloride by the
Hudson reaction.
