标 题:Expedient synthesis of core disaccharide building blocks from natural polysaccharides for heparan sulfate oligosaccharide assembly
发明人：HSIEH-WILSON LINDA C; PAWAR NITIN J; WANG LEI
权利人:CALIFORNIA INST OF TECHN
摘要:Methods for the preparation of oligosaccharide products from polysaccharide starting materials are disclosed. The methods include: hydrolyzing a glucosamine-containing polysaccharide starting material, such as heparin or heparosan, under conditions sufficient to form an oligosaccharide intermediate (e.g., a GlcN-IdoA disaccharide intermediate or a GlcA-GlcN disaccharide intermediate), and converting the oligosaccharide intermediate to the oligosaccharide product. Conversion of the oligosaccharide intermediates to the oligosaccharide products may include one or more esterification, acylation, epimerization, protection, and deprotection steps. Preparation of higher-order oligomers is described, as well as methods for selective oligosaccharide sulfation.

权利人:WAKO PURE CHEM IND LTD
摘要:Azidohalogenobenzyl derivatives of the formula (I) ##STR1## wherein A is a halogen atom, B is a halogen atom or a hydrogen atom, and X is a group reactive with a hydroxy group, methods of protecting hydroxy group(s) using said derivatives, and sugar compounds wherein a hydrogen atom of at least one hydroxy group is substituted by an azidohalogenobenzyl group. According to the present invention, there are provided novel derivatives capable of introducing a group into a compound having hydroxy group(s), which group is useful as a stable hydroxy-protecting group even in solid phase synthesis for the purpose of the extension of sugar chain under continuous acidic conditions and of being removed under mild conditions; sugar compounds protected by using said derivatives; and methods of protecting hydroxy group(s) using said derivatives.

摘要:The present invention provides: a substrate for achieving the highly efficient synthesis of an aryl compound containing a tritylsulfanyl group; a method for producing a compound containing an SF 5 group using the substrate; and others. The present invention is a method for producing an aryl compound containing a tritylsulfanyl group, the method comprising thiotritylating a halogenated aryl compound represented by general formula (1) [wherein A 1 represents an aryl group that may have a substituent or a heteroaryl group that may have a substituent; and X represents a halogen atom] using [(triphenylmethyl)sulfanyl]potassium or [(triphenylmethyl)sulfanyl]sodium to produce an aryl compound containing a tritylsulfanyl group, the aryl compound being represented by general formula (2) [wherein A 1 is the same as A 1 in general formula (1); and Ph represents a phenyl group].
