Preparatory Study for the Synthesis of the Marine Sponge Alkaloids Asmarines A-F: Synthesis of Their Heterocyclic Portions
摘要:
A synthesis of three tricyclic compounds (l c), (2c), and (3c), selected as models for the heterocyclic portions of the marine sponge alkaloids asmarines A-F, has been accomplished through cyclization of the 7-alkyl-6-chloropurine derivatives.

A nitrosopurine ene reaction easily assembles the asmarine pharmacophore and transmits remote stereochemistry to the diazepine‐purine hetereocycle. This reaction generates potent cytotoxins which exceed the potency of asmarine A (1.2 μM IC50) and supersede the metabolites as useful leads for biological discovery.
