Abstract
La presente invención se refiere a un proceso para producir un compuesto dicetónico cíclico acilado siendo este substancialmente un derivado benzoilo substituído de una 1,3-ciclohexanodiona, caracterizado por la redisposición del enol ester correspondiente, en el cual se conduce la redisposición en la presencia de una fuente de cianuro, la cual es un cianuro alcalino metálico, una cianohidrina de una cetona alquilometílica que tiene de 1 a 4 átomos de carbono en el grupo alquilo, cianohidrina de benzaldehido, cianohidrina de ciclohexanona, una cianohidrina de un aldehido alifático con C2-C5, lactonitrilo, un cianuro silil alquilo inferior, ferricianuro de potasio o cianuro de hidrógeno, en donde tal redisposición es conducida a temperaturas de hasta 80 grados C en la presencia de ya sea (a) una cantidad catalítica de una fuente de cianuro y u n exceso molar, con respecto al enol ester, de una base moderada; o b) una cantidad estequiometrica, con respecto al enol ester, de cianuro de potasio o cianuro de litio y una cantidad catalítica de un ester cíclico Crown o un análogo acíclico del mismo.
