## Abstract An auto oxidation‐rearrangement product 4 was isolated from a high dilution reaction of ninhydrin with 3,4,5‐trimethoxyaniline in water. A general synthesis of this compound and its derivatives 4–6 was devised by oxidation of tetrahydroindeno[1,2‐__b__]indol‐10‐ones 1–3 with sodium peri
The structure of the title compound, C 32 H 23 BrN 2 O 3 ÁH 2 O, is stabilized by intramolecular CÐHÁ Á ÁO interactions, and the molecular packing is stabilized by intermolecular CÐHÁ Á ÁO and NÐHÁ Á ÁN hydrogen bonds.
