Clean and efficient assembly of functionalized benzofuro[2,3-c]pyridines via metal-free one-pot domino reactions†
Abstract
A clean and efficient method for the domino synthesis of new functionalized benzofuro[2,3-c]pyridines from easily accessible 2-hydroxychalcones, α-bromo ketones and ammonium acetate is described. Furan and pyridine ring moieties are ingeniously formed in a one-pot operation in this tricyclic system.
