Abstract:The Cover Feature shows the structures of fluorinated furan lignan, namely trifluoromethylated ent‐fragransin C1 and chiral 1,4‐diarylbutanetriol, which is a key intermediate. Using an acid catalyst, chiral trifluoromethylated 1,4‐diarylbutanetriol undergoes chemoselective generation of the benzylic carbocation followed by stereoselective cyclization to provide the furan product with high stereo‐selectivity. The fireworks illustrate the reaction processes and celebrate the accomplishment of the work using “Loi… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
