Abstract

PROCEDIMIENTO DE PREPARACION DE SOLUCIONES DE ACIDOS 7-AMINOCEFALOSPORANICOS. SE SUSPENDE EN UN SOLVENTE ORGANICO UN COMPUESTO DE FORMULA (I), DONDE R1 ES HIDROGENO O ALCOHOXI DE BAJO PESO MOLECULAR Y R2 METILO, ACETOXIMETILO, METOXI, CLORO O UN GRUPO TIOL-HETEROCICLICO. SE ADICIONA GRADUALMENTE UNA AMIDINA-BICICLICA DE FORMULA (II) HASTA ALCANZAR LA DISOLUCION. SE ENFRIA LA MEZCLA Y SE FILTRA. SE AÑADE UN REACTIVO ACILANTE PARA AJUSTAR EL PH. SE AISLA EL PRODUCTO FINAL POR FILTRACION Y SECADO. SE USAN EN LA ELABORACION DE CEFALOSPORINAS ANTIBIOTICAS, COMO PRODUCTOS INTERMEDIOS. *FORMULA*
