Qy. Liu et al., LEWIS-ACID INDUCED REARRANGEMENT OF 2,3-EPOXY AMINES - CHARACTERIZATION OF AZIRIDINIUM ION INTERMEDIATES AND REGIOSPECIFIC RING-OPENING WITH NITROGEN NUCLEOPHILES, Journal of the Chemical Society. Perkin transactions. I, (11), 1994, pp. 1363-1365
The Lewis acid induced isomerisation of 2,3-epoxy amines into the corr
esponding 2-trimethylsiloxymethylaziridinium ions is described; such i
ntermediates have been characterised by H-1 NMR spectroscopy, and reac
t with nitrogen nucleophiles regiospecifically to form 1-substituted 2
,3-diamino alcohols in good to excellent yields and with full stereoch
emical control.
