Exploiting the Synthetic Potential of Sesquiterpene Cyclases for Generating Unnatural Terpenoids
The substrate flexibility of eight purified sesquiterpene cyclases was evaluated using six new heteroatom-modified farnesyl pyrophosphates, and the formation of six new heteroatom-modified macrocyclic and tricyclic sesquiterpenoids is described. GC-O analysis revealed that tricyclic tetrahydrofuran exhibits an ethereal, peppery, and camphor-like olfactoric scent.
Potassium fluoride on alumina: One-pot synthesis of S-allyl-S-methyldithiocarbonates by tandem condensation-alkylation-sigmatropic rearrangement
Allyl alcohols adsorbed on Al2O3-KF at room temperature reacted wit carbon disulfide and iodomethane and gave S-allyl-S-methyldithiocarbonate. Linalool did not give a rearrangement product. With chrysanthemyl alcohol, opening of the cyclopropane ring was observed.
