Copper-Catalyzed Asymmetric Propargylic Alkylation with Oxindoles: Diastereo- A nd Enantioselective Construction of Vicinal Tertiary and All-Carbon Quaternary Stereocenters
Xia, Jin-Tao,Hu, Xiang-Ping
, p. 1102 - 1107 (2020/02/15)
A copper-catalyzed asymmetric propargylic alkylation of propargylic acetates with 3-substituted oxindoles for the stereoselective construction of vicinal tertiary and all-carbon quaternary stereocenters in a 3,3-disubstituted oxindole skeleton has been realized. The reaction proceeded smoothly under the catalysis of Cu(MeCN)4PF6combined with a chiral tridentate ferrocenyl P,N,N ligand, leading to a broad range of optically active 3,3-disubstituted oxindoles in high yields and with excellent diastereo- A nd enantioselectivities.

3-Aminoquinoline-2,4-diones were stereoselectively reduced with NaBH 4 to give cis-3-amino-3,4-dihydro-4-hydroxyquinolin-2(1H)-ones. Using triphosgene (=bis(trichloromethyl) carbonate), these compounds were converted to 3,3a-dihydrooxazolo[4,5-

N-Arylisatins are efficiently prepared by the reaction of 2-oxo-2-(arylamino)acetates and arynes under mild reaction conditions
Novel ring contraction of 3-hydroxy-2,4(1H,3H)-quinolinediones in aqueous alkali. The first convenient route to 2-hydroxyindoxyls
Kafka,Klasek,Kosmrlj
, p. 6394 - 6399 (2007/10/03)
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.
Synthesis of 3-Hydroperoxyindolin-2-ones and Oxidation of Sulphides to Sulphoxides by 3-Hyxdroperoxyindolin-2-ones
Nishio, Takehiko

The 3-hydroperoxyindolin-2-ones 2 were prepared in moderate yields by the dye-sensitized photooxidation of the indolin-2-ones 1.The 3-hydroperoxyindolin-2-ones thus obtained oxidized a series of sulphides 4 selectively to the corresponding sulphoxides 5 without further oxidation to the sulphone.
