Article abstract of DOI:10.1021/jo00183a028

Reaction of methyl 2-furoate with acetyl nitrate afforded the isolation of six adducts whose stereochemistry was determined: (E)- and (Z)-2-carbomethoxy-2-acetoxy-5-nitro-2,5-dihydrofuran, (E)- and (Z)-2-carbomethoxy-4-acetoxy-5-nitro-4,5-dihydrofuran, an
