Abstract: The exclusive formation of 1-substituted-6-⍺-oximinoethylindoles 3a-d from the reaction of 3,6-diacetylindoles with hydroxylamine reveals the chemoselectivity of C₆-acetyl function over that of C₃-acetyl function towards the nucleophilic attack of hydroxylamine. These monooximes 3a-d are stirred with methanesulphonyl chloride in dry pyridine at room temperature to give the novel 5-substituted-7-acetyl-3,6- dimethyloxazolo[4,5-f]indoles 5a-d in good yields. The structures of all these newly synthesised compounds have been confirmed by their spectral and analytical data and they have been screened for antibacterial and antifungal activities.
