Stereoselective Preparation of (E)-Allyl Alcohols via Radical Elimination from anti-γ-Phenylthio-β-nitro Alcohols
Phenylthio and hydroxymethyl groups may be introduced into nitroalkenes stereoselectively by treatment with benzenethiol and aqueous formaldehyde to give anti-γ-phenylthio-β-nitro alcohols, which are converted into (E)-allyl alcohols via radical elimination induced by Bu3SnH.
