Wudl, Fred published the artcileAsymmetric synthesis of chiral sulfoxides. II. Intramolecular oxygen to nitrogen sulfinyl migration, Synthetic Route of 4972-31-0, the publication is Journal of the American Chemical Society (1973), 95(19), 6349-58, database is CAplus.
The conversion of a 1,2,3-oxathiazolidine 2-oxide (I), derived from l-ephedrine, to Me aryl sulfoxides via sulfinamides (II; R = Me, Ph, MeC6H4) was studied in detail. The stereochem. of sulfinyl transfer in an O-sulfinylated ethanolamine (III) was investigated. This rearrangement proceeds via two competitive paths: intramol. and intermol. The intramol. path yields II with retention of configuration at S.
