Abstract

Nuevo procedimiento para preparar una serie de derivados de 7-aminocefalosporina reemplazando un grupo aciloximetilo o carbamoil-oximetilo sustituido o no -sustituido en la posición 3 de un derivado de 7-aminocefalosporina por un grupo tiometilo sustituido. Numerosos derivados de cefalosporina han sido ya preparados y de muchos de ellos se conocen valiosas actividades antibacteriana. Entre los más valiosos de estos derivados de cefalosporina están los derivados que tienen un grupo tiometilo sustituido en la posición 3- sin embargo, los materiales de partida más fácilmente disponibles para preparación de tales derivados de cefalosporina tienen un grupo aciloximetilo o carbamoiloximetilo sustituido o no sustituido en la posición 3 y es necesario por ello reemplazar este grupo por el grupo tiometilo sustituido deseado.
