Abstract

PROCEDIMIENTO DE OBTENCION DE CEFALOSPORINAS. CONSTA DE LAS SIGUIENTES ETAPAS: 1. REACCION DE UN CLORURO DE ACIDO CARBOXILICO ORGANICO CON UN NUCLEO SILILADO (I). 2. CONVERSION DEL GRUPO A ES HIDROGENO. ANTES DE LA ACILACION SE CONVIERTE EL NUCLEO SILILADO EN EL COMPUESTO INTERMEDIO II, POR INARODUCCION DE DIOXIDO DE CARBONO SECO EN UNA SOLUCION DEL NUCLEO SILILADO EN UN DISOLVENTE ORGANICO ANHIDRO A UNA TEMPERATURA COMPRENDIDA ENTRE 0 Y 100GC. HASTA QUE LA REACCION DE CARBONILACION SE COMPLETA. *FORMULA*
