Stereoselective preparation of spirane bridged, sandwiched bisarenes

Preparation of α-oxo derivatives of spiro[4.4]nonane, spiro[4.5]decane and spiro[5.5]undecane derivatives is described. An efficient method for spiroannulation by Rh(I)-catalysed intramolecular hydroacylation provides α,α′-difunctionalised spiro[4.5]decan

Synthesis of 1,6-disubstituted spiro[4,4]nonanes by palladium mediated transmetallation reactions

The 1,6-bis-(o-methoxyphenyl)spiro[4,4]nona-1,6-diene (4) was prepared by a three steps procedure from spirotriflate (1), using palladium(0) mediated cross-coupling reactions with o-methoxyphenyltributyl-stannane. All new products obtained were characteri
