ZnBr2 catalyzed sequential A3-coupling and intramolecular cyclization: One-pot synthesis of 3-aminofurans
ZnBr2 salt was observed to be an effective catalyst to promote domino A3-coupling and intramolecular cyclization for the synthesis of 3-aminofurans from simple and commercially available α-ketoaldehydes, secondary amines, and terminal alkynes as starting materials. This method is compatible with several substrates and attractive, due to the formation of water as a by-product, operational simplicity, atom-economy, shorter reaction time, and inexpensive catalyst.
