A collection of aryl and alkyl 2-(trimethylsilyl)methyl sulfides have been converted to their respective sulfoxides by four different asymmetric oxidizing agents. The chemical yields range from 44–98% while the enantiomeric excesses range from 0–89%. The Davis oxazaziridine (3′S,2R)-(−)-N-(phenylsulfonyl)-(3,3-dichlorocamphoryl)oxaziridine was shown to be superior to the. Modified Sharpless Reagent

thioesters in high yields and purities. The conversion of 2-(trimethylsilyl)ethyl sulfides into synthetically versatile thioesters allows such sulfides to be used as sulfhydryl protectivegroups, since such sulfides are easily prepared and are stable towards many reaction conditions encountered in organicsyntheses.

The reaction of sulfanylmethyllithiums generated from benzylsulfanes and n-BuLi with N,N-dimethylthioformamide followed by the addition of Grignardreagents gave 2-phenyl-2-sulfanyl tertiary amines in moderate to good yields. A range of Grignardreagents involving primary alkyl, aryl, vinyl, and alkynyl Grignardreagents were used. Two carbon–carbon bond-forming reactions were achieved through a one-pot
