Synthesis of the insect pheromone (2S,3S,7RS)-diprionyl acetate by diastereoselective protonation
Ebert, Sophia,Krause, Norbert

The insect pheromone (2S,3S,7RS)-diprionyl acetate (1) was prepared from (S,S)-2,3-dimethylcyclohexanone (2), which in turn was obtained by the 1,4-addition of lithium dimethylcuprate to (S)-(+)-carvone (3) and diastereoselective protonation of the result

(–)-Agelasine F (also known as ageline A) is a diterpene-adenine hybrid natural product isolated from marine sponges (Agelas species) and this compound is known to display cytotoxic activity against a variety of cancer cell lines as well as microorganisms. We herein report the first total synthesis of (–)-agelasine F. The commercially available and inexpensive monoterpenoid (S)-carvone was found to be a highly suitable starting material for the construction of the terpenoid part of the desired agelasine and controlling the stereochemistry of the target compound. Two alternative strategies from (S)-carvone were evaluated. Key-intermediates in the (–)-agelasine F synthesis are believed also to be valuable starting materials for total syntheses of other bioactive marine sponge metabolites. The synthetic route to (–)-agelasine F described herein is more efficient than previously published syntheses of racemic or ent-agelasine F.
