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 :Manganese catalyzed photopolymerization of fluorinated monomers
发明人：ASANDEI ALEXANDRU D
权利人:UNIV CONNECTICUT
摘要:The disclosure discloses initiating systems for the radical polymerization of alkenes, and especially fluorine substituted alkenes. The polymerization is catalyzed by a metal carbonyl, preferably manganese carbonyl. The polymerization is initiated directly from alkyl halides at room temperature under visible white light. The polymers also allow the synthesis of block copolymers. The process comprises polymerizing at least one alkene monomer in the presence of a halide radical initiator, carbonyl catalyst and a solvent, under reaction conditions and for a time sufficient to polymerize the at least one alkene monomer to form a polymer. The present disclosure provides a method for living polymerization of alkene monomers which provides a high level of macromolecular control over the polymerization process and which leads to uniform and controllable polymeric products. This disclosure also provides a method for activating any halide (Cl, Br, I) chain ends of such polymers for the synthesis of block copolymerizations.

摘要:In this invention we are disclosing a process for the synthesis of hydrocchlorofluoro olefins (HCFO) and/or hydrofluoroolefins (HFO). The process is based on the steps of fluorination of hydrochloropropenes or hydrochloropropanes to form hydrochlorofluoropropenes and/or hydrofluoropropenes, followed by gas phase, catalytic fluorination of the hydrochlorofluoropropenes to form hydrofluoropropenes.
