| Abstract: | The dimeric indole alkaloid callichiline ( 2 ), C42H48O5N4, has been isolated from Callichilia (Hedranthera) barteri (HOOK . f.) PICHON along with vobtusine ( 1 ) and beninine ( 3 ). Its chemical reactions and spectral properties have shown that callichiline is made up of the same two monomeric ‘halves’ as vobtusine, that is beninine ( 3 ) and the vincadifformine analogue of beninine. |
