Abstract
Reivindicacion 1: Un proceso para preparar un compuesto de la formula (1), en la que R1 es para-nitrobencilo o alilo y R2 es bencilo o bencilo sustituido; que comprende el paso de hacer reaccionar un compuesto de la formula (2), en la que R1 y R2 son como se definieron con anterioridad; con una sal de yoduro para producir el compuesto de la formula (1). Reivindicacion 2: Un proceso para preparar un compuesto de la formula (3), en la que R1 para-nitrobencilo o alilo; R2 es bencilo o bencilo sustituido; y R3 es alquilo C1-6; que comprende el paso de reaccionar un compuesto de la formula (1), como se describe en la reivindicacion 1, con P(OR3)3 en un solvente. Reivindicacion 4: El proceso de acuerdo con la reivindicacion 2, que además comprende los pasos de: a) calentar dicho compuesto de la formula (3) en un solvente en presencia de LiCl y una base orgánica soluble para formar un compuesto de la formula (4), en la que R1 para-nitrobencilo o alilo; y R2 es bencilo o bencilo sustituido; y b) hacer reaccionar el compuesto de la formula (4) con R4-OH y PX5 para producir los compuestos de la formula (5) en la que R1 es como se definio con anterioridad y R4 es alquilo C1-6 y X es halo. Reivindicacion 13: Un compuesto de la formula (6), en la que R1 es para-nitrobencilo; R2 es bencilo; en donde * representa un centro quiral que representa una configuracion absoluta de (R) o (S); en donde dicho compuesto contiene isomeros (R) y (S) en una proporcion entre 0:1 y 1:0.
