Grela 2nd Generation Chemical Properties,Usage,Production

Reaction

  1. This catalyst is used for an efficient synthesis of HCV Protease Inhibitor, BILN 2061.
  2. The nitro-Grela catalyst is a stable olefin metathesis initiator active in various ring-closing, cross, and enyne metathesis reactions. Its efficiency has been proven in numerous total syntheses of natural and biologically active compounds, and in material science.

Uses

nitro-Grela is a universal catalyst which provides good results in a wide spectrum of olefin metathesis transformations. The catalyst provides high efficiency in cross metathesis (CM) reactions between type 1 olefins and an electron deficient partner. The catalyst is very good for CM of disubstituted internal olefins.

reaction suitability

core: ruthenium
reagent type: catalyst
