Abstract

Procedimiento para la preparacion de una sal de la formula general (I), en la cual X(-) representa un anion inorgánico, m = 1, 2 o 3, y R representaun radical alquilo lineal C1-4, donde: a) se hace reaccionar un correspondienteom ega-amino-alfa-amino ácido, de manera selectivaen su funcion omega-amino de modo de obtener compuestos de la formula general (II); b) se oxida el compuesto de la formula general (II),obteniéndose compuestos de la formula general (III);c) y se cicliza el compuesto de la formula general (III) en ausencia de agua en lapresencia de un ácido, por cierre del anillo, obteniéndose la sal de la formula general (I). Este es un procedimiento, mejorado tanto desde elpuntode vi sta economico como ecologico en comparacion con el estado actual de la técnica, para la preparacion de compuestos de la formula general (I), el cualprocedimiento mejorado ha de permitir al ser aplicado en escala industrial, unproceso cuyo desar rollo sea estable y exento de riesgos. Se obtienen loscompuestos deseados, ello, con muy buenos rendimientos globales, superiores al 70%, sin que se presente desechos (productos secundarios) ecologicamenteobjetables, siendo elprocedimiento, muy fiable. Otra de las ventajas de este procedimiento es que prácticamente todos los flujos de los solventes puedenser recirculados (reciclados), con lo cual la cantidad de productos de desecho, prácticamente inevitables, esreducida a un mínimo posib le.
