标题:Method for the Synthesis of Ionizable Lipids Using a Doubly Alkylated Intermediate

权利人:NANOVATION THERAPEUTICS INC
摘要:Provided herein is a method for the preparation of ionizable, cationic amino lipids using a doubly alkylated nucleophilic intermediate to produce a ketone. The ketone, or a corresponding alcohol, is subjected to one or more synthesis steps to add an ionizable moiety thereto. The method can be advantageously employed for the synthesis of unsymmetrical analogues of the above lipids that would be considerably more difficult to make by alternative strategies. The method can also be used to prepare symmetrical ionizable, cationic amino lipids with fewer steps and/or with the use of fewer hazardous chemicals than known synthesis methods.

摘要:The invention provides new methods for the synthesis of isotopically enriched metal borohydrides, metal tetrahydroundecaborate salts, and decaborane from isotopically enriched 10 B-boric acid or 11 B-boric acid. The invention is particularly useful for synthesis of isotopically enriched sodium or lithium borohydride, MB 11 H 14 (where M is Li, Na, K, or alkylammonium), and decaborane.

标题:Process for the electrochemical synthesis of alpha-saturated ketones
发明人:GARNIER LAURENCE; ROLLIN YOLANDE; PERICHON JACQUES
权利人:POUDRES & EXPLOSIFS STE NALE
摘要:The present invention relates to a process for the electrochemical synthesis of alpha-saturated ketones by electrochemical reduction, in an organic solvent medium, of alpha-saturated organic halides in the presence of CO2 and of a catalyst based on nickel complexed with a bidentate organic ligand containing two nitrogen atoms, such as 2,2'-bipyridine and, optionally, with an ethylenic coligand. The anode, made of a metal chosen from the group consisting of the reducing metals and their alloys, is consumed during the electrochemical reaction whose site it is. It is preferably made of magnesium. This process is simple to use and allows a single-compartment cell to be employed. Alpha-saturated ketones are compounds commonly employed in the chemical industry, particularly as solvents or synthesis intermediates.

标 题 :Synthesis of substituted triphenylenes, useful as discotic liquid crystals

摘要:Unsymmetrically substituted triphenylenes required in the synthesis of polymeric discotic liquid crystals are made using iron (III) chloride in organic solvent at room temperature to effect the oxidative coupling of 1,2-dialkoxybenzenes to 3,3',4,4'-tetraalkoxybiphenyls. This is followed by a reductive workup. The same oxidation-reduction protocol also proves effective in the trimerisation of 1,2-dialkoxybenzenes.

标题 :Process for the synthesis of L-(+)-ergothioneine
发明人:TRAMPOTA MIROSLAV
权利人:PHARMATECH INTERNATIONAL INC
摘要:This invention relates to a novel process for the preparation of optically pure L-(+)-ergothioneine. The process for the chemical synthesis of L-ergothioneine comprises steps which consist of reacting L-histidine alkyl ester with an acid halide, chloroformate or pyrocarbonate in the presence of a base, hydrolysis of the alkyl-(S,Z)-2,4,5-triamidopent-4-enoate to obtain a (S)-alkyl 2,5-diamido-4-oxopentanoate, acid catalyzed hydrolysis of the (S)-alkyl 2,5-diamido-4-oxopentanoate followed by reaction with a metal thiocyanate to obtain the thiohistidine, protection of the sulfur of thiohistidine as the tert-butyl thioether, dialkylation of the primary amine to obtain a tertiary amine, quaternization of the tertiary amine, and removal of the protecting group to obtain the desired (S)-3-(2-mercapto-1H-imidazol-5-yl)-2-(trialkylammonio)propanoate (I). This process affords a better yield and is capable of practical application at large scale.
