Total Synthesis of the Cytotoxic Anhydrophytosphingosine Pachastrissamine (Jaspine B)
摘要:
A short, 8-step synthesis of the marine natural product pachastrissamine has been developed that relies on a diastereoselective aldol reaction between a suitably protected hydantoin and an optically enriched alpha-chloroaldehyde. This synthetic route provides new opportunities for exploring structure activity relationships within this family of natural products.
