    Notes: The reaction of 2 with 2-methoxyethylamine in the presence of ZnCl2 afforded imine 3, which was reduced with NaBH4 to amine 4 without isolation. After deprotection of the carbonyl function by treatment with benzeneseleninic anhydride, ketone 5 was converted to compound 6 with 2-oxobutyric acid and dicyclohexylcarbodiimide. The isodasycarpidone derivative 7, formed by aldol reaction of 6, represents a tetracyclic substructure of strychnos-type alkaloids.

    Notes: Indole Alkaloids, II. - Synthesis of 4-Amino-tetrahydrocarbazol-1-one DerivativesTreatment of 1,2,3,4-tetrahydrocarbazol-1-one with 1,2-ethanedithiol gave the tetrahydrocarbazole 2 which was oxidized with DDQ to compound 3. It was converted into the imine 6 by treatment with n-butylamine and ZnCl2. The imine was directly reduced with NaBH4 to give the amine 7, which was acetylated with benzoyl chloride to yield amide 8. Treatment of 8 with mercury(II) oxide and Et2O·BF3 gave 9.
