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.

权利人:KOREA INST SCI & TECH
摘要:The present disclosure relates to a novel method for preparing an arylnaphthalene lignan compound. In synthesis of arylnaphthalene lignan compounds and derivatives according to the present disclosure, a naphthalene backbone may be constructed first and an aryl group may be introduced at the final stage. Through this, various kinds of derivatives that could not be prepared from the existing methods can be synthesized effectively. Further, the synthesis method according to the present disclosure is appropriate for large-scale production.

标题 :Asymmetric synthesis of α-cycloalkylalkyl substituted methanamines
发明人：ROTH GREGORY; LANDI JOHN
权利人:BOEHRINGER INGELHEIM PHARMA
摘要:This invention relates to process for asymmetrically producing enantiomerically pure α-cycloalkylalkyl substitututed methanamines from α-pinene. One key step of the process of this invention utilizes the oxidation product of α-pinene, hydroxy pinanone, as a chiral auxiliary to direct the stereoselective alkylation of the corresponding ketimine. This invention also relates to key intermediates useful in the processes referred to herein.

标 题 :Sulfoxide ligand metal catalyzed oxidation of olefins
发明人：WHITE M CHRISTINA; AMMANN STEPHEN E; LIU WEI; MA RULIN
权利人:UNIV ILLINOIS
摘要:The enantioselective synthesis of isochroman motifs has been accomplished via Pd(II)-catalyzed allylic C—H oxidation from terminal olefin precursors. Critical to the success of this goal was the development and utilization of a novel chiral aryl sulfoxide-oxazoline (ArSOX) ligand. The allylic C—H oxidation reaction proceeds with the broadest scope and highest levels asymmetric induction reported to date (avg. 92% ee, 13 examples ≥90% ee). Additionally, C(sp 3 )-N fragment coupling reaction between abundant terminal olefins and N-triflyl protected aliphatic and aromatic amines via Pd(II)/sulfoxide (SOX) catalyzed intermolecular allylic C—H amination is disclosed. A range of 52 allylic amines are furnished in good yields (avg. 76%) and excellent regio- and stereoselectivity (avg. >20:1 linear:branched, >20:1 E:Z). For the first time, a variety of singly activated aromatic and aliphatic nitrogen nucleophiles, including ones with stereochemical elements, can be used in fragment coupling stiochiometries for intermolecular C—H amination reactions.
