followed by reaction of the opened intermediate with ethyl acrylate afforded the sulfinate/β-sulfanyl ethyl ester derivative. Selective oxidation with 1 and 2 equiv of (3S)-3-tert-butyl-3-methyl-2-(phenylsulfonyl)oxaziridine or with 3 equiv of DMD led to the isolation of a series of compounds containing a sulfonate and a β-sulfanyl, a β-sulfinyl, and a β-sulfonyl ethyl ester.
