• General Description: Aphidicolin is a tetracyclic diterpene compound with a complex structure featuring a bicyclo[3.2.1]octane ring system and a C16,C17 diol moiety. It is known for its role as a reversible inhibitor of DNA polymerase, particularly in eukaryotic cells, and has been studied for its potential antiviral and antitumor properties. The successful total synthesis of (+)-aphidicolin demonstrates its structural complexity, involving key steps such as hetero-Diels-Alder condensation and Claisen rearrangement to achieve the correct stereochemistry and functional group placement. The compound's confirmed spectral and physical properties align with those of naturally derived aphidicolin, underscoring the validity of the synthetic approach.

Total Synthesis of (+/-)-Aphidicolin and (+/-)-β-Chamigrene

10.1021/jo00180a010

The research focuses on the total synthesis of (+)-aphidicolin and (+)-β-chamigrene, which are complex organic compounds belonging to the tetracyclic diterpene class. The purpose of the study was to develop an efficient synthetic process for these compounds, utilizing a series of chemical reactions including hetero-Diels-Alder condensation, Claisen rearrangement, and solvolytic α-route for the formation of the bicyclo[3.2.1]octane portion of the molecule. The synthesis involved a variety of chemicals such as α-methylene ketones, methyl methacrylate, quinoline, and various ester and ketone derivatives. The conclusions of the research highlighted the successful synthesis of the target compounds, with a particular focus on the rearrangement of intermediates to form the aphidicolane bicyclo[3.2.1]octane ring system, which was a central feature of the (+)-aphidicolin synthesis. The study also detailed the challenges encountered in the synthesis process, such as the introduction of the C16,C17 diol system and the stereochemical control of the hydroxylation of exo-olefinic ketone. The final product, (+)-aphidicolin, was confirmed to have the same physical and spectral properties as an authentic sample, validating the synthetic route developed in the study.
