专利号:US-10040898-B2 优先权日:2016-08-31 标 题:Method for one-step synthesis of functional polyesters by organic catalysis 发明人:GUO KAI; LIU YIHUAN; ZHU NING; HU XIN; FANG ZHENG; FENG WEIYANG; HUANG WEIJUN 权利人:NANJING UNIVERSITY OF TECHNOLOGY 摘要:It relates to the field of synthetic macromolecular chemistry, and discloses a method for one-step synthesis of thiol-functionalized polyester polyols by organic catalysis. This method uses lactone monomer as reaction raw material, thiol-alcohol as initiator, and diphenyl phosphate as organic catalyst to catalyze and synthesize the thiol-functionalized polyester polyols. The present invention provides a method which is simple, inexpensive, easily controllable and environmentally friendly to prepare thiol-functionalized polyester polyols with the easily available and controllable catalyst. The method can selectively catalyze the ring opening polymerization of lactone to prepare thiol-functionalized polyester polyols using the organic catalyst.

专利号:WO-2007003236-A1 优先权日:2005-06-30 标 题:Process for synthesis of complex 2-deoxy-2-iodo pyranosides of high purity, particularly suitable for manufacturing pharmaceutically pure annamycin 发明人:SZEJA WIESLAW; GRYNKIEWICZ GRZEGORZ; FOKT IZABELA 权利人:ZACLAD BADAWCZO PROD SYNTEX; SZEJA WIESLAW; GRYNKIEWICZ GRZEGORZ; FOKT IZABELA 摘要:The method according to the invention comprises using as glycosyl donors high purity 2- deoxy-2-iodo derivatives of sugars of a defined configuration of C-2 carbon with O-alkyl, S- alkyl, O-aryl, S-aryl, O-heteroaryl, S-heteroaryl, O-acyl, O-silyl, O-N-imido, O-P- (phosphino, phosphono, thiophosphono, selenophosphono) groups at the anomeric position, and subjecting them to a condensation reaction with a compound containing a hydroxyl group or a protected hydroxyl group in the presence of electrophilic reagents, followed by deprotection and isolation of a pharmaceutically pure product. The objective of the present invention is to provide a method for preparing complex glycosides by coupling cyclic multifunctional compounds containing hydroxyl functional groups (glycosyl acceptors, including aglycones of natural origin which are known as constituents of active pharmaceutical ingredients) with diastereoisomerically pure 2-deoxy-2-halopyranosyl derivatives containing anomeric substituent capable of exchange under glycosidating conditions, for example by virtue of activation with electrophilic agents. This method substantially simplifies the synthesis of Annamycin. The present invention relies on a regio- and stereoselective reaction of cohalogenating 1,2- unsaturated sugars in the presence of hydroxyl group containing compounds, such as: water, alcohols, phenols, carboxylic acids, silanols, phosphinic acids, phosphoric acids, thiophosphoric acids, selenophosphoric acids, followed by separation of the product with proper C-2 carbon configuration required for the synthesis. As the separation of stereoisomers is carried out at the stage of obtaining a relatively inexpensive intermediate in the form of glycosyl donor, the method of the invention substantially reduces the cost of Annamycin manufacture. Other advantages of the synthesis process of the invention consist in the reduction of the number of stages of the antibiotic manufacture process and in yield increase of the final product.
