The first total synthesis of Furoscrobiculin B is accomplished by construction of the azuleno[6,7-c]furan ring system by base catalysed pinacol-type rearrangement of isonaphthofuran derivative, prepared from suitably functionalized hydrobenzofuran by use of the Furan Ring Transfer (FRT) reaction.
Total synthesis of (±)-furoscrobiculin B, a lactarane
sesquiterpene isolated from basidiomycetes of mushrooms, has been
achieved via an improved synthetic route of our previous work
based on a Furan Ring Transfer (FRT) reaction and base-catalysed
pinacol-type rearrangement.
