Abstract
The reaction of the lithio derivative of novel polyethylene glycol (PEG)‐supported α‐phenylselenopropionate with aldehydes, followed by oxidation–elimination with 30% hydrogen peroxide and then treatment with sodium nitrite, formed PEG‐bound 2‐nitromethyl‐2‐alkenoates. Subsequent cleavage from the PEG efficiently afforded methyl (E)‐2‐nitromethyl‐2‐alkenoates in good yields and high purities.
