Abstract
La presente se refiere a un proceso para la preparación de 2-fenil-2-hidroxi-N-[2-(3-alcoxi-4-hidroxifenil)-etil]-acetamidas de la fórmula (1) en la cual R1 es alquilo; R2 y R3 son cada uno independientemente hidrógeno o alquilo; y R4 es arilo optativamente sustituido o heteroarilo optativamente sustituido; mediante un proceso el cual comprende hacer reaccionar una 2-(3-alcoxi-4-hidroxifenil)-etilamina de la fórmula (2), en la cual R1, R2 y R3 son como se definieron anteriormente con un éster de ácido alfa-hidroxicarboxílico de la fórmula (3) ó una dioxolanona de la fórmula (4), en la cual R4 es como se definió anteriormente, y R5, R6 y R7 independientemente entre sí son alquilo inferior. Los compuestos de fórmula (1) son importantes intermediarios para un grupo de fungicidas derivados de amidas del ácido mandélico.
