Abstract

PROCEDIMIENTO PARA LA OBTENCION DE ISOXAZOLES 3,5-DISUSTITUIDOS. CONSISTE EN LA REACCION DE UNA DIHALOFORMALDOXIMA, TAL COMO DICLOROFORMALDOXIMA O DIBROMOFORMALDOXIMA, CON UN EXCESO DE 2 A 5 VECES DE UN DERIVADO DE 1-ALQUILO, DE FORMULA R-CFH, EN LA QUE R ES HIDROGENO, FENILO O ALQUILO C1-6 QUE PUEDE ESTAR SUSTITUIDO. LA REACCION SE LLEVA A CABO EN UN DISOLVENTE ORGANICO INERTE EN EL QUE ES SOLUBLE EL DERIVADO DE 1-ALQUILO, EN PRESENCIA DE UNA CANTIDAD EQUIMOLECULAR RESPECTO A LA DIHALOFORMALDOXIMA DE UNA BASE ALCALINA, TAL COMO CARBONATO O BICARBONATO SODICO O POTASICO, A LA TEMPERATURA AMBIENTE. ESTOS COMPUESTOS TIENEN APLICACIONES FARMACOLOGICAS POR SUS ACTIVIDADES ANTIHELMINTICA, NEMATOCIDA Y ANTIMICROBIANA, Y COMO INTERMEDIOS PARA LA PREPARACION DE HERBICIDAS.
