标 题 :Process for the industrial synthesis of vinyl and isopropenyl chloroformate and thiochloroformate
发明人：MALFROOT THIERRY A; PITEAU MARC D
权利人:POUDRES & EXPLOSIFS STE NALE
摘要:The invention relates to a process for the industrial scale synthesis of vinyl and isopropenyl chloroformates and thiochloroformates. According to the invention, phosgene or thiophosgene is reacted, at between 20 DEG and 70 DEG C., with a mercury salt XHg(CH2CRO), in which X=Cl or -CH2CRO, where R=H or CH3, in the presence of a solvent or a mixture of solvents having a dielectric constant greater than 10. The process can also be carried out using a mixture of the above solvents with a solvent which is not effective by itself (solvent of low polarity) but which is inexpensive. The yields achieved can exceed 90%.

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.
