Cadinane-type sesquiterpenes, cubebenes, δ-cadinene, cubenol, and epicubenol, as well as two sesquiterpene methyl ethers as minor constituents have also been obtained from th...
In the synthesis of 7-epicubebol (33), allylic tertiary C-H insertion is observed as a significant competing reaction in the intramolecular cyclopropanation of unsaturated terminal epoxide 22. 展开 关键词: Stereocontrolled Intramolecular Epoxides ...
