Intramolecular Fluoroacylation Enabled by TrBF4-Catalyzed Fluoride Recycling
Alkyne- and alkene-tethered acyl fluorides undergo intramolecular carbofluorination via fluoride recycling using catalytic TrBF4. Excellent stereoselectivity is observed for the alkyne addition, enabling access to novel fluorinated indan-2-ones (all ≥95:5 E/Z) and cyclopentan-2-ones (85:15 E/Z). Fluorinated chroman-2-ones and tertiary alkyl fluorides can also be synthesized using this method, comparing favorably to previously reported protocols that employ expensive metal catalysts under harsher conditions.
期刊介绍:
Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
