| Outline of Final Research Achievements |
We have established a concise and rapid synthesis of terpene skeletons of the natural product toward the derivatization of natural products composed of heterocyclic rings and terpene moieties. For the terpene moiety of the natural product, The initial route was limited to a few hundred milligrams in 30 h but was successfully improved to a few grams in about three hours. This route facilitates the large-scale supply of the molecules. For heterocyclic main group element moiety, synthesis and characterization of biologically active pentacoordinate silicon compound was also carried out. Furthermore, a flexible molecular coupling by the new click strategy was developed. Overall, we established new molecular technologies that contribute to the rapid synthesis of functional molecules possessing bioactivity and probe activity.
