Studies of the Reaction between Indole-2,3-diones (Isatins) and Secondary Aliphatic Amines.
摘要:
Simple secondary aliphatic amines react with isatin to yield, depending on the structure, either 2-amino-phenylglyoxamides, such as 2-amino-N,N-dimethyl-phenylglyoxamide, or dialkylammonium salts of 2-aminophenylglyoxylic acids. Reaction of isatin with N,N'-dimethylethylenediamine gave an unusual 2:1 product, whose structure has been determined by X-ray crystallography.

Regio- and stereospecific syntheses of several spiro[pyrrolidine2,3′-oxindole] derivatives by cycloaddition trapping of azomethine ylides generated in situ, via decarboxylative condensation of isatin with α-amino acids or by reaction of secondary amines with isatin, are reported. 2,6-Dibenzylidenecyclohexanone, 2-arylidene-1-tetralone, and arylidenemalononitrile derivatives have been efficiently used

The reaction of isatin, ninhydrin and acenaphthenequinone with primary and secondaryamines gives rise to stereospecific formation of intermediate azomethine ylides which can be trapped by cycloaddition to methyl acrylate or N-methylmaleimide. The regiochemistry of the cycloadditions to methyl acrylate is controlled by both frontier orbital and steric interactions with the latter dominating in the
