Abstract

Se provee un procedimiento para el desenriquecimiento de composiciones enantiomericamente enriquecidas que comprende hacer reaccionar una composicion enantiomericamente enriquecida que comprende por lo menos un primer enantiomero o diastereomero de un substrato que comprende un enlace carbono-heteroatomo, en donde el carbono es un centro quiral y el heteroatomo es un heteroatomo del grupo VI, en la presencia de un sistema catalizador y opcionalmente un promotor de reaccion para dar una composicion de producto que comprende primeros y segundos enantiomeros o diastereomeros del substrato que tiene un enlace carbono-heteroatomo, la relacion de segundo a primer enantiomero o diastereomero en la composicion de producto es mayor que la relacion de segundo a primer enantiomero o diastereomero en la composicion enantiomericamente enriquecida. Substratos preferidos incluyen compuestos de Formula (I) (ver Formula (1)) en donde X representa O, S; R1, R2 cada uno representa independientemente un hidrocarbilo opcionalmente substituido, un hidrocarbilo perthalogenado, un grupo heterociclico opcionalmente substituido; o R1 y R2 se unen opcionalmente a fin de formar un anillo(s) opcionalmente substituido; con la condicion de que R1, R2 se seleccionan de tal manera que * es un centro quiral. En un procedimiento preferido se puede obtener un compuesto de Formula (2) (ver Formula (2)) en donde: X representa O, S; R1, R2 cada uno representa independientemente un hidrocarbilo opcionalmente substituido, un hidrocarbilo perthalogenado, un grupo heterociclico opcionalmente substituido; o R1 y R2 se unen opcionalmente a fin de formar un anillo(s) opcionalmente substituido; con la condicion de que R1, R2 son diferentes.
