摘要:The invention is directed to the cross-metathesis and ring-closing metathesis reactions between geminal disubstituted olefins and terminal olefins, wherein the reaction employs a Ruthenium or Osmium metal carbene complex. Specifically, the invention relates to the synthesis of α-functionalized or unfunctionalized olefins via intermolecular cross-metathesis and intramolecular ring-closing metathesis using a ruthenium alkylidene complex. The catalysts preferably used in the invention are of the general formula n wherein: n M is ruthenium or osmium; n X and X 1 are each independently an anionic ligand; n L is a neutral electron donor ligand; and, n R, R 1 R 6 , R 7 , R 8 , and R 9 are each independently hydrogen or a substituent selected from the group consisting of C 1 -C 20 alkyl, C 2 -C 20 alkenyl, C 2 -C 20 alkynyl, aryl, C 1 -C 20 carboxylate, C 1 -C 20 alkoxy, C 2 -C 20 alkenyloxy, C 2 -C 20 alkynyloxy, aryloxy, C 2 -C 20 alkoxycarbonyl, C 1 -C 20 alkylthio, C 1 -C 20 alkylsulfonyl and C 1 -C 20 alkylsulfinyl.

摘要:The present invention discloses single step, highly enantioselective catalytic oxidative cyclization process for the synthesis of 3-substituted chiral phthalides. In particular, the invention discloses asymmetric synthesis of chiral phthalides via synergetic nitrile accelerated oxidative cyclization of o-cyano substituted aryl alkenes in high yield and enantiomeric excess (ee) in short reaction time. Also, disclosed herein is “one-potâ€? asymmetric synthesis of biologically important natural compounds having 3-substituted chiral phthalide structural framework in the molecule.

摘要:Disclosed is a method for the combined synthesis of at least two vinylic monomers, at least one of which being an acrylic compound, comprising subjecting a monoconjugated alkene-1-carboxylic compound to reaction with a C 2 -C 4 alkene under conditions of olefin cross-metathesis. The invention is particularly useful for extracting value from protein side streams. Upon protein hydrolysis, suitable amino acids (preferably phenylalanine or tyrosine) are subjected to reductive amination so as to form the corresponding alkene-1-carboxylic acid. Preferably after esterification and separation, this is used in cross-metathesis for the concomitant production of styrene resp. hydroxy styrene, and acrylates. The invention is applicable more widely, to the synthesis of olefins on the basis of carbohydrates, naturally occurring phenolic components, natural protein resources, or amino acids obtained from fermentations.
