摘要:4- (2,3- dichlorophenyl) -1,4- dihydro- 2,6- dimethyl- 5- methoxycarbonyl- 3- pyridinecarboxylic acid, a key intermediate in the synthesis of the cardiovascular calcium channel blocker drug 3-butanoyloxymethoxycarbonyl-5- methoxycarbonyl-4- (2,3-dichlorophenyl) -2,6- dimethyl-1,4- dihydropyridine, of purity greater than 97% and essentially free of the corresponding diacid, is prepared by a process involving selective precipitation of its carboxylate via addition of concentrated solutions of alkali metal salts. Similar intermediate mono-carboxylic acids useful in the synthesis of other unsymmetrically substituted dihydropyrine drugs such as nisoldipine, nitrendipine and nimodipine can be similarly prepared and purified.

标 题:Dietary supplement and method for synthesis of same
发明人：WYNN JASON R
权利人:StrongCell LLC
摘要:A dietary supplement and method for synthesis of the same are disclosed. In one embodiment of the method, an NADH component is provided that includes at least partially microencapsulated nicotinamide having nicotinamide blended with water. A supplement component, such as collagen, coenzyme Q10, vitamins, and minerals, is provided. A mixed component, which is a liquid, is formed by mixing the NADH component with the supplement component at ambient conditions. The mixed component is subjected to a fill production process.

发明人：WYNN JASON R
权利人:StrongCell LLC
摘要:A dietary supplement and method for synthesis of the same are disclosed. In one embodiment of the method, an NADH component is provided which includes NADH from about 0.1% to about 0.5% blended with water from about 40% to about 84% both by weight of the dietary supplement. A supplement component from about 9% to about 99% by weight of the dietary supplement is also provided. The supplement component may include collagen in about 2% to about 10%, vitamins in about 0.00001% to about 3%, and minerals in about 0.000002% to about 0.5% all by weight of the dietary supplement. A mixed component is formed by mixing the NADH component with the supplement component at ambient conditions. The mixed component is a liquid at ambient conditions having a pH of less than 4.0. The mixed component is subjected to a cold fill production process.

标题:Electrochemical synthesis of niacin and other N-heterocyclic compounds
发明人：TOOMEY JR JOSEPH E
权利人:REILLY IND INC
摘要:An electrochemical oxidation of a pi-deficient N-heterocyclic precursor compound having an oxidizable organic group attached by a carbon-to-carbon linkage. This precursor compound is at least sparingly water soluble. The preferred electro-oxidation is conducted at an effective anode and in a medium which consists essentially of water, carboxylic acid, and the precursor compound. Preferred are electro-oxidations of substituted pyridine and quinoline bases and a particularly preferred aspect provides a convenient electrochemical synthesis of niacin from 3-methylpyridine.
