Abstract
Los derivados de (2R)-2-desoxi-2-flúor-2-metil-citidina de la fórmula (1) tienen potencial de ser útiles como profármacos de inhibidores potentes de la polimerasa NS5B del virus de la hepatitis C (HCV). Reivindicación 1: Un proceso de obtención del obtención del derivado de (2R)-2-desoxi-2-flúor-2-metilcitidina de la fórmula (1) en la que R¹ se elige entre alquilo C₁₋₄, que consta de los pasos: a) transformar el derivado (2R)-2-desoxi-2-flúor-2-metil-D-ribonolactona de la fórmula (2) en la que R² es fenilo o alquilo C₁₋₄, en el cloruro de (2R)-2-desoxi-2-flúor-2-metil-D-ribofuranosilo de la fórmula (3) en la que R² es fenilo o alquilo C₁₋₄; b) condensar el cloruro de (2R)-2-desoxi-2-flúor-2-metil-D-ribofuranosilo de la fórmula (3) con la N-benzoil-citosina de la fórmula (6a) para formar el derivado de (2R)-N-benzoil-2-desoxi-2-flúor-2-metil-citidina de la fórmula (4) en la que R² tiene el significado definido antes y Bz es benzoílo; c) alcohólisis del derivado de (2R)-N-benzoil-2-desoxi-2-flúor-2-metil-citidina de la fórmula (4) para generar la (2R)-2-desoxi-2-flúor-2-metil-citidina de la fórmula (5); y d) acilar la (2R)-2-desoxi-2-flúor-2-metil-citidina de la fórmula (5) para obtener el derivado de (2R)-2-desoxi-2-flúor-2-metilcitidina de la fórmula (1), caracterizado porque el paso b) de condensación consta de: b₁) la sililación de N-benzoil-citosina de la fórmula (6a) para formar la N-benzoil-citosina sililada de la fórmula (6b) en presencia de un acetato de alquilo C₃₋₄ como disolvente y b₂) la condensación de la N-benzoil-citosina sililada de la fórmula (6b) con el cloruro de (2R)-2-desoxi-2-flúor-2-metil-D-ribofuranosilo de la fórmula (3) en la que R² es fenilo o alquilo C₁₋₄, para formar el derivado de (2R)-N-benzoil-2-desoxi-2-flúor-2-metil-citidina de la fórmula (4) en la que R² tiene el significado definido antes y Bz es benzoílo, en presencia de diclorometano como disolvente y un ácido de Lewis.
