electrophiles including alkyl halides, carbonyl compounds, and sodium iodoacetate. A convenient synthetic method for 4-alkyl- and 5-alkyl-2(5H)-furanones has been developed by using these dianions. A new synthetic approach to trans-3,4-bis(3-hydroxybenzyl)dihydro-2(3H)-furanone, the first lignan found in humans, via a facile reduction of 2(5H)-furanone with Mg-methanol is also decribed.
衍生自 β-羟基砜的二价阴离子对多种亲电子试剂具有高度反应性,包括卤代烷、羰基化合物和碘乙酸钠。已经通过使用这些二价阴离子开发了一种方便的 4-烷基-和 5-烷基-2(5H)-呋喃酮合成方法。一种合成反式-3,4-双(3-羟基苄基)二氢-2(3H)-呋喃酮的新方法,这是人类发现的第一种木脂素,通过用Mg-甲醇轻松还原2(5H)-呋喃酮描述。
