Title (EN) INTERMEDIARY PRODUCTS OF CEPHALOSPORINE, PREPARATION PROCESS THEREOF AND UTILIZATION THEREOF
(FR) PRODUITS INTERMEDIAIRES DE CEPHALOSPORINE, LEUR PROCEDE DE PREPARATION ET LEUR UTILISATION
Abstract:
(EN) Process for preparing intermediary products of cephalosporine having the formula (I) wherein R1 is an acyl group. Modification of a compound having the formula (IV) and/or (IVa) wherein R1 has the same meaning as hereabove and (A), respectively (B) represents a heterocycle having 5 or 6 atoms, and comprising in addition to the N atom one or two other heteroatoms, for example O, N and S, and susceptible of being substituted or ringed with an optionally substituted benzol cycle, with a compound of formula (V) wherein R10 represents hydrogen or an amino protection group.
(FR) Procédé de préparation de produits intermédiaires de céphalosporine de formule (I) où R1-CO représente un groupe acyle. Modification d'un composé de formule (IV) et/ou (IVa) où R1 a la même signification que ci-dessus et (A), respectivement (B) représente un hétérocycle comportant 5 ou 6 atomes, pouvant comporter en plus de l'atome de N un ou deux autres hétéroatomes, par exemple O, N et S, et pouvant être substitué ou annelé avec un cycle benzol le cas échéant substitué, avec un composé de formule (V) où R10 représente un hydrogène ou un groupe de protection amino.
