Abstract
PROCESO PARA LA FABRICACION DE COMPUESTOS DE ESPIRO-HIDANTOINA. CONSISTENTE EN HACER REACCIONAR UN ESTER A-HIDROXI CON 1 A 2 EQUIVALENTES DE UREA Y CON 1 A 2 EQUIVALENTES DE UN ALCOHOLATO ALCALINO EN UN SOLVENTE DE UN ALCANOL INFERIOR PARA OBTENER UNA OXAZOLIDINEDIONA ESPIROTRICICLICA. A CONDICION DE QUE LA INTRODUCCION DE UN NITROCONSTITUYENTE, LA ESTEARIFICACION DE ACIDOS CARBOXILICOS, LA OXIDACION DE SULFUROS ALQUILICOS Y LAS HALOGENACIONES AROMATICAS, SE EFECTUEN DESPUES DE QUE EL COMPUESTO AROMATICO TRICICLICO SE CONVIERTE EN EL COMPUESTO DE OXALIDINEDIONA APROPIADO, Y DE QUE CIERTOS GRUPOS DE PROTECCION INESTABLE PUEDEN UTILIZARSE DURANTE LAS REACCIONES PARA PROTEGER LOS SUSTITUYENTES REACTIVOS. SE EMPLEA EN EL TRATAMIENTO DE COMPLICACIONES DE DIABETES MELLITUS EN PERSONAS Y ANIMALES.
