Reaction of nitrous acid with α,β-unsaturated oximes having the structural fragment of 2-methyl-3-hydroxyimino-1-cyclohexene is described. A set of the oximes studied includes simple monocyclic derivatives (2-methyl-2-cyclohexenone oxime and carvone oxime) as well as more complex bicyclic compounds (car-2-en-4-one oxime and a-muurolen-3-one oxime). The reaction was shown to give allylic nitro compounds
描述了亚硝酸与具有2-甲基-3-羟基亚氨基-1-环己烯的结构片段的α,β-不饱和肟的反应。研究的一组肟包括简单的单环衍生物(2-甲基-2-环己烯酮肟和香芹酮肟)以及更复杂的双环化合物(car-2-en-4-one肟和α-muurolen-3-one肟) )。已显示该反应产生了具有碳骨架保留或具有重排骨架的烯丙基硝基化合物。所得产物的化学结构和立体化学通过1 H,13 C和14 N NMR光谱以及IR和UV数据确定。讨论了反应的可能机理。分子力学和MNDO计算用于机理研究。
