标题 :Synthesis of ruthenium or osmium metathesis catalysts

权利人:CALIFORNIA INST OF TECHN
摘要:The present invention relates to the synthesis of highly active ruthenium and osmium carbene metathesis catalyst in good yield from readily available starting materials. The catalysts that may be synthesized are of the general formula n wherein: n M is ruthenium or osmium; n X and X 1 are independently any anionic ligand; n L and L 1 are any neutral electron donor ligand; and, n R and R 1 are each hydrogen or one of the following substituent groups: C 2 -C 20 alkenyl, C 2 -C 20 alkynyl, C 1 -C 20 alkyl, 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. Optionally, the substituent group may be substituted with one or more groups selected from C 1 -C 5 alkyl, halogen, C 1 -C 5 alkoxy, and aryl. When the substitute aryl group is phenyl, it may be further substituted with one or more groups selected from a halogen, a C 1 -C 5 alkyl, or a C 1 -C 5 alkoxy. Specific synthetic protocols for vinyl alkylidene catalysts wherein R is hydrogen and R 1 is —CHCR 12 R 13 and non-vinyl alkylidene catalysts are also disclosed. In addition to the ease of synthesis (typically a one-step synthesis), the reactions generally may be run at or above room temperature and the resulting products usually may be used without extensive post synthesis purification.

标题 :One-pot synthesis of group 8 transition metal carbene complexes useful as olefin metathesis catalysts
发明人：GRUBBS ROBERT H; MORGAN JOHN P; BENITEZ DIEGO; LOUIE JANIS

摘要:The invention provides a novel method for synthesizing transition metal carbene complexes useful as olefin metathesis catalysts. The method is a convenient one-pot synthesis in which transition metal carbenes are prepared in high yield from readily available starting materials via a dihydrogen complex containing two different anionic ligands, preferably a phosphine and a heteroatom-stabilized carbene. The invention additionally provides a method for synthesizing precursors to carbene ligands useful, inter alia, in the aforementioned one-pot synthesis. The precursors are in the form of trichloromethyl adducts of the formula L 1 -CCl 3 , where L 1 is a heteroatom-stabilized carbene ligand, and are prepared by contacting an unsaturated, ionized analog of L-CCl 3 with a non-nucleophilic base in the presence of chloroform.

摘要:The invention pertains to the use of Group 8 transition metal carbene complexes as catalysts for olefin cross-metathesis reactions. In particular, ruthenium and osmium alkylidene complexes substituted with an N-heterocyclic carbene ligand are used to catalyze cross-metathesis reactions to provide a variety of substituted and functionalized olefins, including phosphonate-substituted olefins, directly halogenated olefins, 1,1,2-trisubstituted olefins, and quaternary allylic olefins. The invention further provides a method for creating functional diversity using the aforementioned complexes to catalyze cross-metathesis reactions of a first olefinic reactant, which may or may not be substituted with a functional group, with each of a plurality of different olefinic reactants, which may or may not be substituted with functional groups, to give a plurality of structurally distinct olefinic products. The methodology of the invention is also useful in facilitating the stereoselective synthesis of 1,2-disubstituted olefins in the cis configuration.

摘要:The syntheses of the natural products, avrainvillamide and stephacidin B, are provided. The α,β-unsaturated nitrone functionality of avrainvillamide and its 3-alkylidene-3H-indole 1-oxide core is shown to covalently and reversibly bond to heteroatom-based nucleophiles. This capability may allow these molecules to bind active site nucleophiles and may provide the basis for designing potent and selective enzyme inhibitors. Both avrainvillamide and its dimer stephacidin B have been reported to exhibit antiproliferative activity, and avrainvillamide has been reported to exhibit antimicrobial activity against multi-drug resistant bacteria. Avrainvillamide has been found to target cytoskeleton-linking membrane protein (CLIMP-63) thereby preventing cells from undergoing mitosis. The invention provides syntheses of these natural products as well as analogs of these natural products and their functional cores. The compounds of the invention may be used in the treatment of diseases such as cancer, autoimmune diseases, and bacterial infection.
