readily available and cheap aryl bromides and sodium iodide as the starting materials to synthesize valuable functionalized dihydrobenzofurans and indolines in good to excellent yields with broad functional‐group compatibility. As examples to demonstrate the utility of this protocol, gram‐scale reactions and further transformations of the products were accomplished towards the synthesis of bioactive
The SmI2âH2Oâamine mixture has been shown to be effective for intramolecular couplings providing diastereoselectivities of up to 100% de in the coupling of O-cyclohexenyliodophenol derivatives into heterocycles.
