Large-Scale Synthesis of a Niche Olefin Metathesis Catalyst Bearing an Unsymmetrical N-Heterocyclic Carbene (NHC) Ligand and its Application in a Green Pharmaceutical Context

A large-scale synthesis of known Ru olefin metathesis catalyst VII featuring an unsymmetrical N-heterocyclic carbene (NHC) ligand with one 2,5-diisopropylphenyl (DIPP) and one thiophenylmethylene N-substituent is reported. The optimised procedure does not require column chromatography in any step and allows for preparation of up to 0.5 kg batches of the catalyst from simple precursors. The application profile of the obtained catalyst was studied in environmentally friendly dimethyl carbonate (DMC). Although VII exhibited low efficiency in cross-metathesis (CM) with electron-deficient partners, good to excellent results were noted for substrates featuring easy to isomerise C?C double bonds. This includes polyfunctional substrates of medicinal chemistry interest, such as analogues of psychoactive 5F-PB-22 and NM-2201 and two PDE5 inhibitors—Sildenafil and Vardenafil. Finally, a larger scale ring-closing metathesis (RCM) of a Vardenafil derivative was conducted in DMC, allowing for straightforward isolation of the expected product (23 g) in high yield and with low Ru contamination level (7.7 ppm).

METAL-LIGAND COMPLEX, OLEFIN POLYMERIZATION CATALYST DERIVED THEREFROM, AND OLEFIN POLYMERIZATION METHOD UTILIZING THE CATALYST

A metal-ligand complex has formula (I): wherein J, L, M, R1, R2, R3, R4, X, p, q, and r are defined herein. The metal-ligand complex is useful as a catalyst or catalyst precursor for olefin polymerization.

Metathesis Catalysts and Processes for Use Thereof

This invention relates to a metathesis catalyst compound comprising an asymmetrically substituted N-heterocyclic carbene (NHC) metathesis catalyst and a process to make linear alpha-olefins comprising contacting a feed material and an optional alkene (such as ethylene) with said catalyst, where the feed material is a triacylglyceride, fatty acid, fatty acid alkyl ester, and/or fatty acid ester, typically derived from biodiesel.
