Of organic compounds,nitronic esters are a group of unusual compounds.Accordingto their chemical formula（R<sub>1</sub>R<sub>2</sub>C=NO<sub>2</sub>R<sub>3</sub>）,they might be formally obtained fromcondensation of aci-nitro compounds（intronic acids）and alcohols with an equivalentamount of water eliminated.In fact,neither could nitronic esters be produced by thismethod,nor could they be hydrolyzed into nitronic acids and alcohols.Since they
