Abstract
Fischer's method is used to synthesize a number of 1-keto-1, 2, 3, 4-tetrahydrocarbazole and 1-keto-1, 2, 3, 4 -tetrahydro-9-methylcarbazole derivatives. The oximes of these ketocarbazoles are converted to the corresponding 1-amino-1, 2, 3, 4-tetrahydro-9-methylcarbazole hydrochlorides, 1-hydroxy-9-methylcarbazole is obtained by dehydrogenating a ketocarbazole derivative with palladium on barium sulfate.
