Abstract

Los sulfóxidos de cefalosporina son intermediarios ampliamente utilizados en la síntesis de antibióticos de cefalosporina. Por ejemplo, los sulfóxidos de cefalosporina son útiles en el procedimiento global para convertir los compuestos de 3-metil-3-cefem(desacetoxicefalosporinas) a compuestos antibióticos de metil-3-cefem-3-sustituídos. Esta funcionalización de los compuestos de 3-metil-cefem procede a través de la isomerización del 3-metil-3-cefem a 3-metil-2-cefem, la funcionalización del grupo 3-metilo activado del compuesto 2-cefem, por ejemplo, con bromo, seguido por oxidación del compuesto metil-2-cefem-3-sustituído al sulfóxido. La oxidación al sulfóxido provoca la isomerización del producto 2-cefem- a 3-cefem.
