چکیده

The first total synthesis of bussealin E, a natural product with a unique cycloheptadibenzofuran scaffold, is reported. A strategy inspired by a proposed biosynthesis was employed whereby a diphenylpropane derivative underwent an oxidative phenolic coupling to forge the tetracyclic ring system. The synthesis of the diphenylpropane featured a key sp2-sp3 Hiyama coupling between a vinyldisiloxane and a benzylic bromide.

Palladium-catalysed cross-coupling of vinyldisiloxanes with benzylic and allylic halides and sulfonates.

The Hiyama cross-coupling reaction is a powerful method for carbon-carbon bond formation. To date, the substrate scope of this reaction has predominantly been limited to sp(2)-sp(2) coupling reactions. Herein, the palladium-catalysed Hiyama type cross-coupling of vinyldisiloxanes with benzylic and allylic bromides, chlorides, tosylates and mesylates is reported. A wide variety of functional gro...

Bioinspired total synthesis of (±)-yezo'otogirin C.

The first and protective group-free total synthesis of (±)-yezo'otogirin C has been achieved from 3-methyl-4-prenylcyclohex-2-enone in eight steps with 23% overall yield. The tricyclic core of (±)-yezo'otogirin C was established via a bioinspired oxidative cascade cyclization strategy using Mn(II)/Mn(III) and O2, followed by reduction of the peroxy-bridged intermediate using thiourea in refluxi...
