Title (EN) PROCESS FOR PREPARING CEPHALOSPORIN INTERMEDIATES
(FR) PROCEDE DE PREPARATION D'INTERMEDIAIRES DE CEPHALOSPORINE
Abstract: front page image
(EN)Processes for the preparation of stable, crystalline cephalosphorin intermediates of formula (I) and formula (II), wherein X is HI or HCl, and Nu and Nu + are certain N-containing heterocyclic rings attached via a sulfur atom or a ring nitrogen atom, respectively, which are substantially free of the $g(D)2 isomer; processes for intermediates in the preparation of the above compounds; and processes for the preparation of broad-spectrum cephalosporin antibiotics.
(FR)Procédés de préparation d'intermédiaires crystallins stables de céphalosporine correspondant aux formules (I) et (II), où X est HI ou HCl, et Nu et Nu + sont certains anneaux hétérocycliques contenant N reliés via un atome de soufre ou un atome d'azote cyclique, respectivement, qui sont essentiellement dépourvus de l'isomère $g(D)2; procédé permettant d'obtenir des intermédiaires dans la préparation des composés ci-décrits; et procédés de préparation d'antibiotiques à base de céphalosporine à large spectre.
