P. Merino et al., A general method for the vinylation of nitrones. Synthesis of allyl hydroxylamines and allyl amines, SYN COMMUN, 30(16), 2000, pp. 2989-3021
An examination of the vinylation of several nitrones is presented. Whereas
a complete diastereofacial discrimination was observed upon the addition of
vinyl organometallic reagents to alpha-alkoxy nitrones, the same reaction
with alpha-amino nitrones pave syn adducts in all cases, with the only exce
ption of a L-serine-derived alpha-amino monoprotected nitrone. The obtained
allyl hydroxylamines were easily transformed into synthetically valuable a
llyl amines.
