Abstract

Un procedimiento para la preparación de un derivado de sesquiterpeno, representado por la fórmula (I) **fórmula** donde R1 representa un átomo de hidrógeno, un grupo alquilo inferior o un grupo alcanoílo inferior, R4 y R6 , que pueden ser iguales o diferentes, representan cada uno de ellos un grupo hidroxilo o un grupo alcanoiloxi inferior, R5 representa un grupo hidroxilo, y R2 y R3 o ambos representan un grupo carboxilo y sus sales farmacéuticamente aceptables, cuyo procedimiento consiste en someter a reacción de oxidación el correspondiente compuesto de fórmula (I) donde R2 y, R3 o ambos representan un grupo formilo y , opcionalmente, alquilar o acilar los compuestos obtenidos donde R1 es hidrógeno y/o R4 y R6 son grupos hidroxilo, para obtener los correspondientes compuestos donde R1 es un grupo alquilo inferior o alcanoliloxi inferior y/o R4 y R6 son grupos alcanoiloxi inferior, y si se desea, convertir el producto obtenido en sus sales.
