标 题 :Stereoselective synthesis of intermediates and synthesis of quinagolids
发明人:RYBERG PER; PINESCHI MAURO; COMPARINI LUCREZIA
权利人:FERRING BV
摘要:Disclosed is a method for preparing compounds with improved stereoselectivities. The described compounds are useful intermediates and may find particular application in the synthesis of compounds containing an octahydrobenzoquinoline moiety (e.g. an octahydrobenzo[g]quinoline moiety), such as quinagolide and its derivatives. Also disclosed is a method for stereoselectively (e.g. enantioselectively) preparing an intermediate used in the existing manufacturing process for the synthesis of quinagolide this intermediate also finding utility in the synthesis of other compounds containing an octahydrobenzo[g]quinoline moiety, in particular those having a substituent at the 3- position on the octahydrobenzo[g]quinoline.

摘要:Provided is a stereoselective synthesis of an intermediate for the preparation of the heterocyclic derivative as a Cap-dependent endonuclease inhibitor. The synthesis process has the advantages of simple operation, higher yield and relatively controllable steroselectivity, such that it is suitable for large-scale production.

标 题 :Process to obtain benzoxazines to be used for the synthesis of ofloxazine, levofloxazine and derivatives
发明人:CARRETERO GONZALVEZ JUAN-CARLO; VICIOSO SANCHEZ MERCEDES; GARCIA RUANO JOSE-LUIS
权利人:ETILO DERIVADOS
摘要:A process to obtain benzoxazines useful for the synthesis of Ofloxazine, Levofloxazine and derivatives. The benzoxacines (I) where Xb is an halogen and R 1 is H, alkyl or alkenyl of up to 6 atoms of C or aryl, can be obtained by means of cycling a compound of formula (II) through the reaction with triphenylphosphine and ethyl azodicarboxilate. The compounds of formula (II) can be obtained through the reaction of a compound (III) with an adequate epoxide. Through the use of the adequate chiral epoxide it is possible to obtain the enantiomerically desired intermediate and, therefore and selectively, it is possible to obtain the desired final product with the adequate enantiomeric form without the need to carry out a resolution stage. n The Compounds (I) are useful and key intermediates for the synthesis of the antimicrobials Oflixazine and Levofloxazine. ##STR1##

标题:Low temperature, high yield synthesis of hydrogen terminated highly porous amorphous silicon, and nanomaterials and composites from Zintl phases
发明人:WAGNER MICHAEL J; BANEK NATHAN A
权利人:UNIV GEORGE WASHINGTON
摘要:The present disclosure relates to an improved process for the synthesis of hydrogen terminated silicon from Zintl phases. The hydrogen terminated silicon is useful, for example, as explosives, chemical and biochemical sensors, optoelectronic materials and Li-ion battery anode ion storage materials. The present disclosure also relates to an improved process for the synthesis of nanomaterials and composites from Zintl phases. The nanomaterials and composites are useful, for example, as ion storage materials.
