Alternative synthetic approaches to (±)-euryfuran via the furan ring transfer reaction

Two effective synthetic approaches to (±)-euryfuran 1 are described. One synthetic route makes use of sequential furan ring transfer reaction type I and type III as key steps followed by Eschenmoser-type [3,3]sigmatropic rearrangement, and another route proceeded through furan ring transfer reaction type I and annulation with ethyl vinyl ketone subsequently.

A new approach to annelated furans. The total synthesis of (+/-)-euryfuran

A new approach to annelated furans has been developed starting from ketones.Formylation of the enolate, protection of the aldehyde function as its (phenylthio)- or (n-butylthio)methylene derivative and addition of methoxy(phenylthio)methyllithium gave add
