Preliminary conformational data based on X-ray diffraction, 1H NMR and molecular mechanics is also presented with the aim of understanding the observed high regioselectivity. The facile synthesis of 6,12-O-dimethylerythromycin A, a standard to assess clarithromycin purity in quality control processes, is reported

This result is understood in terms of internal charge-transfer species expressly favored by Et2N ...

The topotactic phosphate/phosphonate exchange of the ligand into gamma-zirconium phosphate led to an organic–inorganic-layered material which revealed an excellent matrix to achieve the efficient sensitization of emitting lanthanides.

Electrochemical measurements and the observation of heavy quenching of the Ru(bpy)3 luminescence manifested strong interactions between the active moieties. Attempts to include the dyads into inorganic matrices derived from zirconium phosphate are reported.
