标 题:Total synthesis of prostaglandin J natural products by stereoretentive metathesis
发明人：LI JIAMING; CHEN XU; AHMED TONIA S; STOLTZ BRIAN M; GRUBBS ROBERT H
权利人:CALIFORNIA INST OF TECHN
摘要:This invention relates generally to the synthesis of Δ12-Prostaglandin J product using stereoretentive ruthenium olefin metathesis catalysts supported by dithiolate ligands. Δ12-Prostaglandin J products were generated with excellent selectivity (>99% Z) and in moderate to high/good yields (47% to 80% yield; 58% to 80% yield).

标题 :Synthesis of terminal alkenes from internal alkenes via olefin metathesis
发明人：SCHRODI YANN; PEDERSON RICHARD L; KAIDO HIROKI; TUPY MICHAEL J
权利人:ELEVANCE RENEWABLE SCIENCES
摘要:This disclosure relates generally to olefin metathesis, and more particularly relates to the synthesis of terminal alkenes from internal alkenes using a cross-metathesis reaction catalyzed by an olefin metathesis catalyst. According to one aspect, for example, a method is provided for synthesizing a terminal olefin, the method comprising contacting, in the presence of a ruthenium alkylidene metathesis catalyst, an olefinic substrate comprised of at least one internal olefin with a cross metathesis partner comprised of an alpha olefinic reactant, under reaction conditions effective to allow cross-metathesis to occur, wherein the reaction conditions include a reaction temperature of at least 35° C. The methods, compositions, reactions and reaction systems herein disclosed have utility in the fields of catalysis, organic synthesis, and industrial chemistry.

标题 :Synthesis of terminal alkenes from internal alkenes and ethylene via olefin metathesis
发明人：SCHRODI YANN
权利人:MATERIA INC
摘要:This invention relates generally to olefin metathesis, and more particularly relates to the synthesis of terminal alkenes from internal alkenes using a cross-metathesis reaction catalyzed by a selected olefin metathesis catalyst. In one embodiment of the invention, for example, a method is provided for synthesizing a terminal olefin, the method comprising contacting an olefinic substrate comprised of at least one internal olefin with ethylene, in the presence of a metathesis catalyst, wherein the catalyst is present in an amount that is less than about 1000 ppm relative to the olefinic substrate, and wherein the metathesis catalyst has the structure of formula (II) n nwherein the various substituents are as defined herein. The invention has utility, for example, in the fields of catalysis, organic synthesis, and industrial chemistry.
