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.
乙氧基羰基亚甲基三苯基正膦与衍生自 2,6-二-叔丁基-4-硝基苯酚和醇的酰基硝基酯反应得到 α,β-不饱和羧酸酯。当使用1,3-丁二醇或1,6-己二醇的单酰基硝基酯时,得到(E)-5-羟基-2-己烯酸乙酯或(E)-8-羟基-2-辛烯酸乙酯。
