The synthesis of the bisbenzannelated spiroketal core 6 of γ-rubromycin 1 from the substituted nitrostyrene 20 was achieved by using a novel Nef-type reaction mediated by Pearlmanâs catalyst. The precursor 28 was synthesised from readily prepared starting materials using Henry condensation chemistry. The product 6 was found to exist in two conformations in solution as shown by NMR spectroscopy.

A series of small-sized model π-conjugated oligomers have been prepared from thienylene and phenylene or dimethylor dimethoxy-substituted phenylene units. Crystallographic data for the methoxylated compound show a quasi-planar conformation with a non-covalent S–O interaction. The resulting strong conjugation in the gas phase has also been highlighted by UV/photoelectron spectroscopy and theoretical
