The title reaction involves a 1,4-migration of the sulfinyl oxygen atom when treated with the trimethylsilyl halides and proceeds in good yield and with high enantioselec-tivity. In the case of TmsCl redistillation is needed. — (GARCIA RUANO*, J. L.; ALEMAN, J.; ARANDA, M. T.; AREVALO, M. J.; PADWA, A.; Org. Lett. 7 (2005) 1, 19-22; Dep. Quim. Org., Univ.
