The first example of a retro-Henry type reaction is reported using 3-hydroxy-3-((3-methyl-4-nitroisoxazol-5-yl)methyl)indolin-2-ones which are prepared via catalyst-free Henry reaction of 3,5-dimethyl-4-nitroisoxazole and isatin. These compounds were used

A facile strategy for the synthesis of isatins in high yield from N-alkyl-2-oxo-acetanilides has been developed via Friedel-Crafts alkylation using FeCl3 as catalyst under air. This reaction proceeds through direct intramolecular addition and oxidation in one pot. Also this methodology is operationally simple, atom economical, and environment friendly.

The reductive coupling of isatins with ketones and aldehydes by Zn-TiCl4 in THF gave two- and four-electron reduced products, 3-hydoxy-3-(1-hydoxyalkyl)oxindoles and 3-alkylideneoxindoles, selectively by controlling the reaction conditions. Alt

A new, efficient Cu-catalyzed intramolecular C-H oxidation/acylation method has been developed for the synthesis of substituted indoline-2,3-diones (isatins). In the presence of CuCl2 and O2, a variety of formyl-N-arylformamides underwent the tandem reaction to afford the corresponding indoline-2,3-diones in moderate to good yields. It is noteworthy that the reaction serves as the first example of transition-metal-catalyzed transformation for the preparation of indoline-2,3-diones.
