A synthetic route towards a novel hexabenzocoronene-based helical nanographene motif was developed. A hexaphenylbenzene precursor was therefore designed, which cannot undergo, due to steric restrictions, a complete planarization reaction. This precursor was transformed under oxidative cyclodehydrogenation conditions to a π-extended [5]helicene, which was fully characterized including X-ray diffraction analysis.

The synthesis of (S,S)-1,2-bis(3,5-di-tert-butylphenyl)ethane-1,2-diol (98.6% ee), which should be useful as a chiral ligand of catalysts in asymmetric inductions, is described.
On the effect of cyclodextrin on the Z/E-selectivity of Wittig reactions with semistabilized ylides

The Z/E-selectivity of Wittig reactions between semistabilized ylids and aromatic aldehydes is affected by the addition of host molecules such as cyclodextrins (CD). An increase in the Z-selectivity from 57 to 92% has been reached with DMF as solvent and
