TLDR
The literature structure of the reaction product form ninhydrin and 2-aminophenol is corrected in this article, which yields only monosubstituted products, and the literature structure is corrected.
Abstract
Die Umsetzungen von Ninhydrin mit Dimethoxyanilinen und mit reaktiven Aromaten werden durchgefuhrt um zu sehen, ob die mit 2-Anisidin beobachteten Reaktionen auf andere Verbindungen ubertragbar sind. Es werden jedoch stets nur Monosubstitutionsprodukte der eingesetzten Aromaten gefunden. Die in der Literatur angegebene Formel fur das Reaktionsprodukt aus Ninhydrin und 2-Aminophenol wird korrigiert. Investigation of Ninhydrin Reaction The reactions between ninhydrin and dimethoxyanilines and other reactive aromatics are performed in comparison to the reactions with 2-anisidine. They yielded only monosubstituted products. The literature structure of the reaction product form ninhydrin and 2-aminophenol is corrected.

Serendipitous one-pot synthesis of brand-new, bowl-shaped molecular architecture from phloroglucinol and ninhydrin

TL;DR: In this article, a bowl-shaped molecular architecture was constructed from the reaction of ninhydrin and phloroglucinol in acetic acid in a one-pot reaction and the bipolarofacial nature of this compound was confirmed by its X-ray structure.

Selective Methylation of the Ninhydrin-Phenol Adducts with I 2 in MeOH

TL;DR: The formation of ninhydrin-phenol adducts and chemical transformations of them have been studied by as discussed by the authors and othergroups, and the results have shown that the formation of the adduct can be improved with selective methylation.

I2 catalyzed Friedel–Crafts alkylation reaction of substituted anilines with ninhydrin: formation of novel products and their antimicrobial evaluation

TL;DR: In vitro antimicrobial activity evaluation of the synthesized molecules against eight bacterial and four fungal strains revealed that four of them possess duel efficacies (bactericidal as well as fungicidal).

Zur Kenntnis der Ninhydrin‐Reaktion, 2. Mitt.: Das farbige Reaktionsprodukt aus Ninhydrin und 2‐Methoxyanilin

TL;DR: In this paper, the structure of the coloured ketimine, obtained by reaction of 2-methoxyaniline with ninhydrin, is determined by NaBH4-reduction to the three stereoisomeric 2-aminoindan-1,3diols.
