标 题:Novel synthesis of methyl-2-fluoroacrylate
发明人：BRUNKE JESSICA; FISCHER MICHAEL; WÖSSNER JAN STEPHAN
权利人:VIFOR INT AG
摘要:The present invention relates to novel synthesis methods of methyl 2-fluoroacrylate (MFA) which is a key precursor for the production of Veltassa® (Patiromer). The methods according to the invention are conducted by reacting an α-substituted β-hydroxy propionic acid derivative (I) via one or more intermediate steps involving one or more α-, β-substituted propionic acid derivatives (II) to obtain MFA (III).

标 题:One pot synthesis of 5,10-dihydrophenazine compounds and 5,10-substituted dihydrophenazines
发明人：GIRI PUNAM; BYKER HARLAN J; BAUMANN KELVIN L
权利人:GENTEX CORP
摘要:Dihydrophenazines and bis(dihydrophenazines) are prepared in high yield under commercially viable reaction conditions by reacting a catechol with a 1,2-diaminoaryl compound, wherein either the catechol or the 1,2-diaminoaryl compound is provided in at least 50% molar stoichiometric excess. The product may be oxidized to the corresponding phenazine, but is preferably derivatized at one or both of the 5,10-positions to form a monosubstituted or disubstituted dihydrophenazine or bis(dihydrophenazine). Most preferably, 5,10-dialkyl-5,10-dihydrophenazines are prepared starting from catechol and 1,2-diaminoaryl compound in a one pot synthesis. The products are useful as dyes, and in particular as chromophores in electrochromic systems.

权利人:CALIFORNIA INST OF TECHN
摘要:Disclosed are ruthenium and osmium carbene compounds which are stable in the presence of a variety of functional groups and which can be used to catalyze olefin metathesis reactions on strained and unstrained cyclic and acyclic olefins. Specifically, the present invention relates to carbene compounds of the formula ##STR1## wherein: M is Os or Ru; R and R 1 are independently selected from hydrogen and substituent groups C 2 -C 20 alkenyl, C 2 -C 20 alkynyl, C 1 -C 20 alkyl, aryl, C 1 -C 20 carboxylate, C 2 -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 or C 1 -C 20 alkylsulfinyl; each substituent group optionally substituted with C 1 -C 5 alkyl, a halogen, C 1 -C 5 alkoxy or with a phenyl group optionally substituted with a halogen, C 1 -C 5 alkyl or C 1 -C 5 alkoxy; X and X 1 are independently selected from any anionic ligand; and L and L 1 are each trialkyl phosphine ligands where at least one of the alkyl groups on the phosphine is a secondary alkyl or a cycloalkyl. A broad array of metathesis reactions are enabled including ring-opening metathesis polymerization of cyclic olefins, ring closing metathesis of acyclic dienes, cross metathesis involving at least one acyclic or unstrained cyclic olefin, depolymerization of unsaturated polymers and synthesis of telechelic polymers.

权利人:FOSS BENTE J; NADOLSKI GEOFFRY T; LOCKWOOD SAMUEL F
摘要:A method is described for synthesizing and administering carotenoid compounds with improved antioxidant characteristics. In some embodiments, extension or improvement of conjugation may be employed in structural modification of carotenoids. In other embodiments, reduction of ring/chain steric hindrance may improve the lambda max, and hence, the overall antioxidant capability, of particular compounds. In other embodiments, introduction and/or increase in synthetic handles for conjugation may improve the stoichiometric ratios of conjugating moieties to the polyene backbone. The methods may be used to improve natural and/or synthetic compounds for medicinal application in the treatment of disease.
