Expect the upexpected: A transition‐metal‐free approach to access chromone derivatives has been developed. The intramolecular O‐arylation of substituted 1‐(2‐haloaryl)‐propane‐1,3‐diones in DMF in the presence of K2CO3 gave the corresponding target products in good to excellent yields (see scheme; DMF=N,N′‐dimethylformamide).
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.
