Abstract
PROCEDIMIENTO PARA LA OBTENCION DE ENANTIOMEROS DE MONOESTERES DE ACIDOS DICARBOXILICOS OPTICAMENTE ACTIVOS, BAJO SEPARACION DE UN ENANTIOMERO, CARACTERIZADO PORQUE SE SOMETE EL MONOESTER DE PARTIDA A UNA TRANSPOSICION INTRAMOLECULAR Y, EN CASO DADO, SE SEPARA EL ENANTIOMERO DESEADO, OBTENIENDOSE UNA INVERSION DEL SENTIDO DE ROTACION DEL MONOESTER EMPLEADO. LA TRANSPOSICION SE LLEVA A CABO BAJO LAS CONDICIONES DE UNA TRANESTERIFICACION Y EL ENANTIOMERO DESEADO SE SEPARA MEDIANTE CRISTALIZACION. LA CRISTALIZACION DEL ENANTIOMERO DESEADO SE LLEVA A CABO DURANTE LA TRANSESTERIFICACION, TRANSFORMANDOSE EL MONOESTER EMPLEADO COMPLETAMENTE EN EL ENANTIOMERO DESEADO.
