Synthesis of aspidospermidine alkaloids from 1,2,3,4- tetrahydrocarbazole: Total stereoselective synthesis of (±)-18- noraspidospermidine

The reactivity of the 1,2,3,4-tetraliydrocarbazol-4-one derivatives has been analysed and applied to the synthesis of (±)-18-noraspidospennidine (1b). Tiffs was synthesised, starting from 4-(1',3'-dioxolan-2'- yl)cyclohexanone which was successively trans
