Preparation of 2-nitro-2-cyclohexenone acetal starting from 2-nitrocyclohexanone acetal has been reported for the first time. This compound as well as 3-nitro-2-cyclohexenone acetal , whose synthesis has been reported by us earlier, react with a variety of nucleophiles to form highly functionalised intermediates. One of them viz. is converted into a bicyclic α- methylenen-γ-lactone using radical chemistry
首次报道了从2-硝基环己酮缩醛开始制备2-硝基-2-环己烯酮缩醛。这种化合物以及3-硝基-2-环己烯酮缩醛,其合成已被我们较早报道,它与多种亲核试剂反应形成高度官能化的中间体。其中之一,即。使用自由基化学将其转化为双环α-亚甲基-γ-内酯。
