The first preparation of the unstable 1-hydroxy-2,3-dimethylindole, andstructural determination of its air-oxidized product,3-hydroxy-2,3-dimethyl-3H-indole N-oxide
1-Hydroxy-2,3-dimethylindole (1) has been prepared for the first time. Under atmospheric oxygen, 1 was converted rapidly into 3-hydroxy-2,3-dimethyl- 3H-indole N-oxide (2). The structure was deduced, based on its products obtained by the reaction with Ac2O in pyridine and confirmed by X-ray single crystallographic analysis
