Various 2(5H)-furanone and furan derivatives were synthesized from 3-(phenylthio)propenal by a one-pot process via carbonyl addition of a range of organometallic reagents and subsequent sulfide-directed α-lithiatin followed by electrophilic trapping. This methodology was successfuly applied to the syntheses of quercus lactone and 2, 5-diarylfuran natural products.
通过一锅法工艺,通过一系列有机金属试剂的羰基加成,随后进行硫醚导向的α-锂化,并最终进行亲电捕获,从3-(苯硫基)丙烯醛合成了各种2(5H)-呋喃酮和呋喃衍生物。该方法成功应用于栎素和2,5-二芳基呋喃天然产物的合成。
