标 题 :Method of synthesis and purification of citrulline
发明人：BULL JAMES ALAN; FISCHER HOLGER CHRISTIAN; KAISER KARL JUERGEN; MONNOT-CHASE BETTE
权利人:ASKLEPION PHARMACEUTICALS LLC
摘要:This invention provides for synthesis of citrulline from a transition metal complex of ornithine using cyanate to derivatize the terminal amino group of ornithine. The invention also provides improved methods for purification of citrulline produced by reaction of cyanate with ornithine via the steps of reprecipitation of copper complex of citrulline, removal of the complexing metal by sulfide precipitation, activated carbon adsorption and antisolvent crystallization.

摘要:Disclosed is a polycyclic azide desulfurizer, including the following raw materials in parts by mass: 20-35 parts of an alcohol amine, 20-35 parts of an amide, and an aldehyde, which is 10-15 parts of a small-molecule aldehyde or 20-35 parts of a polyaldehyde. Also disclosed is a method for synthesis of the polycyclic azide desulfurizer, including: mixing an alcohol amine with an amide and stirring, heating, adding a catalyst I dropwise, and performing reaction to obtain a monocyclic triazine, heating the monocyclic triazine, mixing with a polyaldehyde and stirring, adding a catalyst II dropwise, and performing coupling while stirring; alternatively, mixing a small-molecule aldehyde with an amide and stirring, heating, adding a catalyst I dropwise, and performing reaction, adding an alcohol amine, adding a catalyst II dropwise, and performing coupling while stirring; and separating a by-product from a product obtained after the coupling out, and purifying the product.
