Front Cover: All-Carbon Quaternary Center Containing Tetrahydro-5H-benzo[c]fluorenes via Highly Stereoselective Transannular Carbocation Cyclization (Chem. Asian J. 11/2025)
Pulchritudinous Butterfly and Blossoming Flowers: As illustrated in the artwork, the key butterfly-like [6/5] bicyclic carbocation intermediate was accessible from the achiral benzannulated cyclononene tertiary alcohol via acid-catalyzed transannular carbocation cyclization. Subsequent nucleophilic addition occurred with high stereoselectivity to afford the all-carbon C11b quaternary center-containing tetrahydro-5H-benzo[c]fluorene. More details can be found in article number e202500300 by Poonsakdi Ploypradith and co-workers.
期刊介绍:
Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics.
Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews.
A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal.
Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
