Condensation of isatin with diketones
Tetrahedron, 1959Abstract The condensation of isatin with enolisable acyclic and alicylcic 1:3-diketones has been investigated and the structures of the acylated cinchoninic acids obtained have been determined. The condensation of acetonylacetone with potassium isatate is also described.

ChemInform Abstract: Remote Activation of the Nucleophilicity of Isatin.
ChemInform, 2014AbstractMichael addition of the isatin imine (I) to aliphatic 1,4‐ketoesters requires a much longer reaction time than the one to aromatic 1,4‐ketoesters.

A Role for Isatin Azomethine Imines as a Dipolarophile in Cycloaddition Reactions.
Organic Letters, 2020An unusual [2 + 3] cycloaddition of isatin azomethine imines (AIs) and in situ generated azaoxyallyl cations has been developed. It is the first example where AIs serve as the [C,O] 2-atom synthon in organic synthesis.

Anodic Methoxylation of Isatin
Zeitschrift für Naturforschung B, 1998Abstract Anodic metoxylation of isatin was investigated. The product formed contained a unique 3a.7a-dihydroindole ring system. 3a,7a-Dihydro-(Z)-3a,7a-dimetoxyisatin was isolated and characterized with a variety of spectroscopic methods.
