标 题 :Enzymatic synthesis of chiral amines using -2-amino propane as amine donor
发明人：WU WEI; BHATIA MOHIT B; LEWIS CRAIG M; LANG WEI; WANG ALICE L; MATCHAM GEORGE W
权利人:CELGRO
摘要:2-Aminopropane is used as the amine donor in the stereoselective synthesis of a chiral amine from a ketone with a transaminase. In a typical embodiment, (S)-1-methoxy-2-aminopropane is prepared by bringing methoxyacetone into contact with a transaminase in the presence of 2-aminopropane as an amine donor until a substantial amount of methoxyacetone is converted to (S)-1-methoxy-2-aminopropane and 2-aminopropane is converted to acetone. In a second embodiment, L-alanine is prepared by bringing pyruvic acid into contact with a transaminase in the presence of 2-aminopropane as an amine donor.

摘要:Embodiments herein relate to apparatus and systems for phenolic and ketone synthesis and methods regarding the same. In an embodiment, a method of producing phenolics and ketones is included. The method can specifically include forming a reaction mixture comprising nanocrystalline cellulose (NCC) and water. The method can also include contacting the reaction mixture with a metal oxide catalyst at a temperature of 350 degrees Celsius or higher and a pressure of at least about 3200 psi to form a reaction product mixture. The reaction product mixture can include at least about 20 wt. % phenolics and at least about 10 wt. % ketones as a percentage of the total mass of nanocrystalline cellulose (NCC). Other embodiments are also included herein.

摘要:The instant invention is a route to stereospecific 3-substituted 5-membered ring isomers of Formula (A). The final products are useful as agents in the treatment of epilepsy, faintness attacks, hypokinesia, cranial disorders, neurodegenerative disorders, depression, anxiety, panic, pain, neuropathological disorders, gastrointestinal disorders such as irritable bowel syndrome (IBS), inflammation especially arthritis, sleep disorders, premenstrual syndrome, and hot flashes. The invention provides novel routes to synthesize stereoselectively analogs of gabapentin (Neurontinâ„¢) of Formulas (I), (II), (III), and (IV) wherein R is C 1 -C 10 alkyl or C 3 -C 10 cycloalkyl and pharmaceutically acceptable salts thereof.
