Towards the biomimetic synthesis of bipleiophylline
Bipleiophylline is a cytotoxic indolomonoterpenic alkaloid recently isolated from the bark of Alstonia angustifolia (Apocynaceae).1 This is probably one of the most complex indole structures that can be encountered in nature. Of particular interest for us is the assembly of the aromatic central core of bipleiophylline that we wish to mimic in a biomimetic way. The progress towards the total synthesis of this intriguing natural substance in which we are currently engaged will be presented.
