| Abstract: | A facile and atom-economic method for the synthesis of 3a,6a-dihydro-furo2,3-b]furan derivatives and polysubstituted furans starting from furylcarbionls has been developed. This protocol involved a domino Claisen rearrangement/dearomatizing electrocyclic ring-closure/aromatizing electrocyclic ring-opening sequence. |
