We report on the layer-by-layer assembly and electrochemical properties of 4-aminothiophenol (P-ATP) and ytterbium(III) trifluoromethanesulfonate hydrate (Yb(OTf)(3)) film supported on a gold surface. The fabricated film was characterised electrochemically using redox couples Fe(CN)(6)(3-/4-), complemented with imaging using atomic force microscopy

We present here a protocol for the synthesis of the dihydropyrimidine (DHPM) derivative monastrol, which is known to be a specific mitotic kinesin Eg5 inhibitor. By applying controlled microwave heating under sealed-vessel conditions, the synthesis via the one-pot three-component Biginelli

The enantioselective Friedel-Crafts addition of a variety of indoles catalyzed by bis(oxazolinyl)pyridine-scandium(III) triflate complexes (Sc(III)-pybox) was accomplished utilizing a series of beta-substituted alpha,beta-unsaturated phosphonates and alpha,beta-unsaturated 2-acyl imidazoles. The acyl phosphonate products were efficiently transformed into esters and amides, whereas
