  S-Oxidation products of (+)-thiomicamine-derived oxazolines—promising substrates in the synthesis of alkyl methyl sulfoxides

  摘要：

  Highly stereoselective oxidation of the 4-methylthio substituent in oxazolines 2-4, derived from (+)-thiomicamine 1, performed using the Kagan procedure and with the vanadium/chiral salen catalytic system, afforded R-s and S-s diastereomeric sulfoxides 5-7, respectively. The reaction of sulfoxide R-s-6 with n-butyl- and tert-butyllithium reagents produced the corresponding butyl methyl sulfoxides in high enantiomeric excess and with an (S) absolute configuration, albeit in moderate yields.
