Abstract

La presente invencion se refiere a un procedimiento novedoso para preparar derivados de 2-ciclopentenol cis-O-protegidos-substituidos que comprende, (a) disolver una 2-ciclopentanona 4-O-protegida en un solvente adecuado; y (b) tratar la solucion con un ácido Lewis adecuado y un agente de reduccion adecuado a una temperatura de aproximadamente -10 degree C a aproximadamente 20 degree C. Los derivados de 2-ciclopentenol cis-4-O-protegidos-substituidos son utiles intermediarios en la preparacion de varios análogos de ciclopentanil y ciclopentanil purina, los cuales son utiles como inmunosupresoras y en la preparacion de varías prostaglandinas.
