Stereoselective Synthesis of Alcohols, I Synthesis of One-Carbon Homologous Allyl Alcohols from Aldehydes or Ketones
The high yield conversion of aldehydes and ketones 2 to the one-carbon homologous allyl alcohols 3 is achieved by condensation to the vinyl sulfoxides 7, isomerisation to the allyl sulfoxides 9, and subsequent sigmatropic rearrangement.
