Molecular machine: A family of loaded molecular winches were designed and synthesized as prototypes for mechanical studies at the single-molecule scale. The molecular winch structure derives from a molecular motor based on a ruthenium complex and is covalently linked to a series of molecular loads such as triptycene, fullerene and porphyrin fragments.

Abstract In the improvedsynthesis of 6-[(ethylthio)methyl]-1H-indazole (5), the mesylate intermediate is replaced by the bromide derivative, which increases the overall yield (six steps) by a factor of 3.
