aldehyde or carboxylic acid, Jones oxidation of 5-substituted-2-furylethanols gives rise to high yields of the corresponding dihydro-2-(2-oxoethyl)furan-3(2H)-ones, following Achmatowicz-type oxidative ring opening and subsequent reclosure by a 5-exo Michael addition of the pendant hydroxy group to the enedione function. Other oxidation methods such as a Swern reaction give lower yields of the same products
在取代了Achmatowicz-之后,5-取代的-2-呋喃乙醇的琼斯氧化而不是产生相应的醛或羧酸,而导致相应的二氢-2-(2-氧代乙基)呋喃-3(2 H)-一的高产率。氧化型开环,随后通过侧羟基的5- exo Michael加成至二烯酮功能而重新闭合。其他氧化方法(例如Swern反应)会降低相同产品的收率,而高邻苯二甲酸镁倾向于生成中间的二烯,而IBX倾向于生成呋喃醛。
