Abstract
UN PROCESO PARA PRODUCIR N-TERT-BUTI-PIPERACINACARBOXAMIDA OPTICAMENTE ACTIVA, UTIL COMO, POR EJEMPLO, UN INTERMEDIARIO EN MEDICINAS CON UNA ALTA PUREZA OPTICA POR LA RESOLUCION OPTICA DE (R,S)-N-TERT-BUTIL-PIPERACINACARBOXAMIDA CON EL USO DE UN ACIDO LACTICO, MELICO O TARTARICO OPTICAMENTE ACTIVO. EL ANTIPODO RESTANTE COMO UN ANTIPODO INUTIL EN EL PASO DE LA RESOLUCION OPTICA DE ARRIBA, PUEDE SER UTILIZADO EFICAZMENTE MEDIANTE LA RACIMACION OPTICAMENTE ACTIVA DE N-TERT-BUTILPIPERACINACARBOXAMIDA EN LA PRESENCIA DE UN COMPUESTO BASICO Y EFECTUANDO OTRA VEZ LA RESOLUCION OPTICA.
