The invention relates to novel metathesis catalysts of the formula (I) a process for making the same and their use in metathesis reactions such as ring closing or cross metathesis. The invention further relates to a process for the manufacture of a macrocyclic compound of formula (VII) which have the potential to be useful as HCV protease inhibitors.

A new preparation of ketenes for intramolecular cycloadditions involves a one-pot synthesis from the appropriate carboxylic acid to the ketene cycloaddition product. A tosylate leaving group rather than the conventional halide ion provides several advantages.
The invention relates to a novel process for the preparation of Ruthenium metathesis catalysts of the formula
Ruthenium metathesis catalysts have been widely applied in the synthesis of macrocyclic drug compounds.
