标题:Synthesis of 4,7-dialkyl chromogenic glycosides of N-acetylneuraminic acids

摘要:The present invention provides an improved method of preparing a 4,7-di-O-alkyl chromogenic ketoside of N-acetylneuraminic acid (Neu5Ac) for use in detecting influenza virus types A and B. The ketosides are substrates that are selectively cleaved by a neuraminidase on influenza virus, but not be neuraminidases found on other viruses or on bacteria. The synthesis is efficient and provides large quantities of the ketoside for commercial development. The synthesis includes a step of alkylating the 4- and 7-hydroxyl groups of a protected alkyl ester alkyl ketoside derivative of Neu5Ac by a process that comprises contacting the derivative with a composition comprising an alkyl halide to form a 4,7-di-O-alkyl protected alkyl ester alkyl ketoside derivative of Neu5Ac. The synthesis alternatively includes protecting the 8- and 9-hydroxyl groups of an alkyl ester alkyl ketoside derivative of Neu5Ac by forming an 8,9-epoxide protected alkyl ester alkyl ketoside derivative of Neu5Ac.

标题:Methods for the synthesis of organic sulfides by using sulfides and organic sulfur-indium complexes
发明人：LEE PHIL-HO
权利人:LEE PHIL-HO; KNU INDUSTRY COOPERATION FOUND
摘要:The present invention relates to a novel synthesis method for the formation of carbon-sulfur bonds by the reaction of an organic sulfur-indium complex with nucleophile in the presence of a palladium catalyst. The present invention provides a synthesis method to prepare several kinds of organic sulfides which are difficult to be prepared by the conventional synthesis methods. A short reaction time and quantitative yield are the advantages of this method. In addition, several kinds of organic sulfide can be prepared by the selection of nucleophile and organic sulfur-indium complex to be used.
