Abstract
Un proceso para preparar epoxido quiral opticamente enriquecido de la formula (I), en donde R1, R2 y R3 son seleccionados independientemente cada uno de H, R, R-CO- y R-O-CO, cada R independientemente que es sustancialmente un grupo hidrocarburo de hasta 20 átomos de carbono, y X es un grupo alquilo o cicloalquilo de hasta 10 átomos de carbono, con la condicion de que -CO-X no sea enolizable, el cual comprende la epoxidacion asimétrica de un alqueno proquiral correspondiente de la formula (II): R1R2C=CR3-CO-X, por reaccion de un oxidante en la presencia de un catalizador quiral. Muchos epoxidos enriquecidos opticamente (I) son novedosos.
