Facile synthesis of 3a,6a-dihydro-furo[2,3-b]furans and polysubstituted furans involving dearomatization of furan ring via electrocyclic ring-closure.
A facile and atom-economic method for the synthesis of 3a,6a-dihydro-furo[2,3-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.
