On the Reactions of Furan-2,3-diones with Oxindole (=1,3-Dihydro-2H-indol-2-one) and Lawesson Reagent. Synthesis of New 1,3-Dihydro-2H-indol-2-ones, Bis-furanones, and Bis-pyrrolones

Lactone analogues of 3‐substituted oxindoles (=1,3‐dihydro‐2H‐indol‐2‐ones) and nonbenzoid oxa‐analogous isoindigoid or nonbenzoid isoindigoid dyes were prepared by the reactions of furan‐2,3‐diones with oxindole and Lawesson reagent (Schemes 1 and 3), respectively. So, new derivatives of 2‐oxobutanoic acid, bis‐furanone, and bis‐pyrrolone, which are potentially biologically active compounds, were
通过呋喃-2,3-二酮与羟吲哚和呋喃的反应制备3-取代的羟吲哚的内酯类似物(= 1,3-二氢-2 H-吲哚-2-酮)和非苯甲酰氧类似异靛类或非苯甲酰异靛类染料。Lawesson试剂(方案1和3)。因此,首次合成了具有潜在生物活性的2-氧代丁酸,双呋喃酮和双吡咯烷酮的新衍生物。
