- PREPARATION OF α,β-UNSATURATED CARBOXYLIC ACID ESTERS BY THE REACTION OF ACI-NITROESTERS WITH ETHOXYCARBONYLMETHYLENETRIPHENYLPHOSPHORANE
-
The reaction of ethoxycarbonylmethylenetriphenylphosphorane with aci-nitroesters derived from 2,6-di-t-butyl-4-nitrophenol and alcohols afforded α,β-unsaturated carboxylic esters.When mono-aci-nitroester of 1,3-butanediol or 1,6-hexanediol was used, (E)-ethyl 5-hydroxy-2-hexenoate or (E)-ethyl 8-hydroxy-2-octenoate was obtained.
