标题:Process for synthesis of amidoacids using a cobalt catalyst and a bidental phosphine ligand
发明人：LIN JIANG-JEN
权利人:TEXACO INC
摘要:A process is disclosed for producing N-acetyl-aminoacid which comprises reacting a feedstock from the group consisting of simple olefins, acetamide and synthesis gas with a catalyst comprising a cobalt-containing compound promoted by a bidental-phosphine ligand in a solvent at a pressure of 500 psi or greater and a temperature of 50 DEG C. or greater. The presence of the ligand increases both reaction rate and cobalt catalyst stability.

标 题:Synthesis of omega functionalized products
发明人：GONZALEZ RAMON; CHEONG SEOKJUNG; CLOMBURG JAMES M
权利人:GONZALEZ RAMON
摘要:The use of microorganisms to make omega- and/or omega-1-functionalized products through an iterative carbon chain elongation pathway that we call a reverse beta oxidation pathway. The pathway uses omega-functionalized CoA thioesters as primers and acetyl-CoA as the extender unit in a non-decarboxylative Claisen condensation, and then uses beta oxidation or fatty acid synthesis enzymes to complete the cycle, via reductase, dehydratase and reductase reactions. Various termination enzymes that act on the functionalized beta-keto acyl-CoA intermediates of the pathway and produce omega or omega-1 functionalized products. The action of termination enzymes on such intermediates yield a large variety of products.

摘要:The use of microorganisms to make omega- and/or omega-l-functionalized products through an iterative carbon chain elongation pathway that we call a reverse beta oxidation pathway. The pathway uses omega-functionalized CoA thioesters as primers and acetyl-CoA as the extender unit in a non-decarboxylative Claisen condensation, and then uses beta oxidation or fatty acid synthesis enzymes to complete the cycle, via reductase, dehydratase and reductase reactions.

标题 :Iterative platform for the synthesis of alpha functionalized products
发明人：GONZALEZ RAMON; CLOMBURG JAMES M; CHEONG SEOKJUNG
权利人:UNIV RICE WILLIAM M
摘要:The use of microorganisms to make alpha-functionalized chemicals and fuels, (e.g. alpha-functionalized carboxylic acids, alcohols, hydrocarbons, amines, and their beta-, and omega-functionalized derivatives), by utilizing an iterative carbon chain elongation pathway that uses functionalized extender units. The core enzymes in the pathway include thiolase, dehydrogenase, dehydratase and reductase. Native or engineered thiolases catalyze the condensation of either unsubstituted or functionalized acyl-CoA primers with an alpha-functionalized acetyl-CoA as the extender unit to generate alpha-functionalized β-keto acyl-CoA. Dehydrogenase converts alpha-functionalized β-keto acyl-CoA to alpha-functionalized β-hydroxy acyl-CoA. Dehydratase converts alpha-functionalized β-hydroxy acyl-CoA to alpha-functionalized enoyl-CoA. Reductase converts alpha-functionalized enoyl-CoA to alpha-functionalized acyl-CoA. The platform can be operated in an iterative manner (i.e. multiple turns) by using the resulting alpha-functionalized acyl-CoA as primer and the aforementioned alpha-functionalized extender unit in subsequent turns of the cycle. Termination pathways acting on any of the four alpha-functionalized CoA thioester intermediates terminate the platform and generate various alpha-functionalized carboxylic acids, alcohols and amines with different β-reduction degree.

摘要:Addition of phosphine ligands can produce high yields of tetraphenoxymethane, TPM, and diphenylcarbonate, DPC, in short reaction times and improved reaction rates by a copper-induced condensation of phenol and carbon disulfide, CS 2 . Either aromatic or aliphatic substituted phosphine ligands can be employed. The copper(I) oxide utilization is significantly improved in reactions containing phosphine ligands, such that yields exceeding 100% tetraphenoxymethane are observed. Some of the sulfur-containing byproduct is transferred to the phosphine in the form of phosphine sulfide.
