  Novel Ring Contraction of 3-Hydroxy-2,4(1H,3H)-quinolinediones in Aqueous Alkali. The First Convenient Route to 2-Hydroxyindoxyls

  摘要：

  Ring contraction of 3-hydroxy-2,4(1H,3H)-quinolinediones (1) in aqueous potassium hydroxide resulted in the formation of 2-hydroxyindoxyls and/or dioxindoles. The choice of N-substituent and the reaction conditions govern the chemoselectivity of the reaction. N-Phenyl-substituted derivatives 1 give 2-hydroxyindoxyls, while N-alkyl- and N-benzyl-substituted derivatives afford the corresponding dioxindols. On the basis of byproduct analysis, as well as independent experiments, the most plausible reaction mechanism is proposed.

  摘要：

  3-Alkyl/aryl-3-hydroxy-1H,3H-quinoline-2,4-diones (2) were transformed into isomeric 3-acyloxy-2,3-dihydro-1H-indol-2-ones (3) by thermally induced molecular rearrangement. All products were characterized by their H-1 NMR, C-13 NMR, and IR spectra.

  starting compounds, C‐debutylation was also observed. If a Bn group is present at C(3), rapid C‐debenzylation of the starting thiocyanates occurred, yielding [1,3]oxathiolo[4,5‐c]quinoline‐2,4‐diones, and mixtures of mono‐, di‐, and trisulfides derived from 4‐hydroxy‐3‐sulfanylquinoline‐2‐ones. The reaction mechanism of all of the transformations is discussed. All new compounds were characterized by IR
