Microwave-assisted domino access to C2-chain functionalized furans from tertiary propargyl vinyl ethers
Tertiary propargyl vinyl ethers armed with an electron-withdrawing group (amide or ester) at the tertiary propargylic position have been efficiently transformed into trisubstituted C2-chain functionalized furans. The metal-free domino transformation involves a microwave-assisted tandem [3,3]-propargyl Claisen rearrangement/5-exo-dig O-cyclization reaction. The manifold can be performed in a one-pot fashion from the primary components (1,2-ketoester/1,2-ketoamide or tertiary propargyl alcohols). © 2011 American Chemical Society.
