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.

标 题:Synthesis of fluorinated radiopharmaceuticals via electrochemical fluorination
发明人：SADEGHI SAMAN; HE QINGGANG; LEBEDEV ARTEM
权利人:UNIV CALIFORNIA
摘要:Provided herein are methods and compositions for the electrochemical selective radiofluorination of aromatic molecules. The resulting fluorine-18 labeled compounds are ideal radionuclides for use in Positron Emission Tomography (PET); they are also difficult to radiolabel efficiently and with high specific activity using existing approaches. For example, radiopharmaceuticals such as [F18]L-DOPA, which is indispensable in PET brain disease imaging, may be made electrochemically with high radiochemical yield and high specific activity using 18F-. The invention process described herein opens new possibilities and provides wider access to PET tracers such as 18F-L-Dopa, since 18F- is much more widely available than the 18F 2 , currently used for synthesis of electron rich substrates.

发明人：NELSON GUNNER E
权利人:ETHYL CORP
摘要:In the direct synthesis process for producing NaAlH4 (pressure hydrogenation of Na and Al in a liquid phase reaction medium at an elevated temperature) advantages are realized by insuring that the initial reaction mixture contains a small amount of water and/or an alcohol. In particular, the induction period is shortened. And, the time, trouble and expense of purifying and pre-drying the reaction medium are avoided.
