Abstract

PROCEDIMIENTO PARA LA OBTENCION DE DERIVADOS DE LOS ACIDOS AMINOSULFONICOS DE FORMULA (I), EN DONDE X, JUNTO CON LOS ATOMOS DE CARBONO A LOS QUE ESTA ENLAZADO, SIGNIFICA UN ANILLO CARBOCICLICO O HETEROCICLICO; Y REPRESENTA EL RESIDUO DE UN COMPUESTO QUE CONTIENE HIDROGENO ACTIVO, TRAS LA ELIMINACION DE DICHO ATOMO DE HIDROGENO, Y "N" ES UN NUMERO ENTERO COMPRENDIDO ENTRE 0 Y 3. CONSISTE EN HACER REACCIONAR UN NITROTIOL DE FORMULA (II) CON UN COMPUESTO QUE CONTENGA HIDROGENO ACTIVO: HY, DONDE X, Y Y "N" TIENEN LOS SIGNIFICADOS SEÑALADOS ANTERIORMENTE. LA REACCION SE LLEVA A CABO CALENTANDO LOS DOS COMPONENTES EMPLEANDO CASI SIEMPRE UN DISOLVENTE MUTUO. UNA VEZ FINALIZADA LA REACCION, EL PRODUCTO SE SEPARA DEL DISOLVENTE MEDIANTE FILTRACION. EN EL COMPUESTO DE FORMULA (III), PREFERENTEMENTE Y REPRESENTA RADICALES, TALES COMO -OH2, -OR3 O -NR CUADRADO R CUBO, EN LOS QUE R ELEVADO A 1 ES UN RADICAL HIDROCARBONADO, OPCIONALMENTE SUSTITUIDO, Y R CUADRADO Y R CUBO SON HIDROGENO O UN RADICAL HIDROCARBONADO, OPCIONALMENTE SUSTITUIDO. *FORMULA*
