Lewis acid mediated elimination and rearrangement reactions of α-chlorosulfides derived from phenylthio-substituted 4,5-dihydrofuran-3(2H )-ones.
摘要:
用硫酰氯将苯硫基取代的 4,5-二氢呋喃-3(2H)-酮高度非对映选择性地转化为δ-氯硫化物。用等量的路易斯酸处理这些氯化物后,呋喃-3(2H)-酮产物会发生消除和芳基迁移。δ-乙酰氧基硫化物衍生物也有类似的表现。研究人员还测定了一种具有代表性的δ-氯硫化物和一种新型环亚磺化产物的 X 射线晶体结构。

Phenylthio-substituted 4,5-dihydrofuran-3(2H)-ones were converted into α-chlorosulfides in a highly diastereoselective manner with sulfuryl chloride. Treatment of the chlorides with stoichiometric amounts of Lewis acids gave furan-3(2H)-one products resulting from elimination and aryl group migrations. Similar behaviour was observed with an α-acetoxy sulfide derivative. The X-ray crystal structures of a representative α-chlorosulfide and of a novel, ring sulfenylated product were determined.
