Abstract
Un procedimiento para la preparación de nuevos derivados de beta-lactama de formula (**formula**) donde x es s, SO o SO2, R es un grupo orgánico de hasta 20 átomos de carbono y A es un grupo tal que CO2A representa un grupo ácido carboxílico o una sal o ester del mismo, cuyo procedimiento consiste en hacer reaccionar un éster del ácido clavulanicos con un compuesto de formula H-S-R donde R es el definido en relación con la formula en presencia de un catalizador ácido, en un disolvente inerte, a una temperatura comprendida entre -80 y +30ºC, y después, opcionalmente, realizar una o mas de las siguientes etapas: a) desesterificar el ester asi producido para formar el ácido libre o salificado de formula; b) reesterificar el ácido libre o salificado así producido para dar otro ester de formula; c) oxidar el sulfuro obtenido con un perácido, en un disolvente inerte, para obtener el correspondiente sulfoxidi o sulfona de formula .
