摘要：

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.
