Abstract

METODO DE PRODUCIR DERIVADOS DEL ACIDO 7-AMINO-3-ALCOXIMETIL-3-CEFEM-4-CARBOXILICO. CONSISTE EN HACER REACCIONAR UN COMPUESTO DE FORMULA (II) CON UN COMPUESTO DE FORMULA R-OH, EN PRESENCIA DE TRIFLUORURO DE BORO O DE UN COMPLEJO DE ESTE, PARA OBTENER DERIVADOS DEL ACIDO 7-AMINO-3-ALCOXIMETIL-3-CEFEM-4-CARBOXILICO DE FORMULA (I), EN LA QUE R ES UN GRUPO ALQUILO INFERIOR. LA REACCION SE EFECTUA EN UN DISOLVENTE ORGANICO, TAL COMO NITRILO ORGANICO COMO ACETONITRILO O PROPIONITRILO, UN NITROALCANO TAL COMO NITROMETANO, O UNA SULFONA, TAL COMO SULFOLAN, Y A UNA TEMPERATURA COMPRENDIDA ENTRE 0 Y 70GC. TIENEN APLICACIONES FARMACEUTICAS POR SUS EFECTOS ANTIBIOTICOS. *FORMULA*
