Abstract

2-Alkyl-2-phenyl-3, 3-dimethylindolines, obtained by 1, 2 organolithium addition to 2-phenyl- 3, 3-dimethyl-3H-indole, are converted into a new series of aminoxyls by oxidation with m- chloroperoxybenzoic acid. Attempts to synthesise, in a similar way, suitable precursors such as 1, 2-dihydro-2-phenyl-2-alkylbenzothiazole, 1, 2-dihydro-2-phenyl-2-alkylbenzoxazole and 1, 2-dihydro-2-phenyl-2-alkyl-4H-3, 1-benzoxazin-4-one for other new aminoxyls ...
