Latest Patents
One of Dominique's latest patents involves the N-demethylation of morphinan alkaloids. This patent discloses a continuous flow system for the N-demethylation of compounds containing tertiary N-methylamines, such as morphinan alkaloids. Specifically, it details the process of N-demethylation of oxymorphone-3,14-diacetate or 14-hydroxymorphinone-3,14-diacetate using highly active catalytic palladium (0) under elevated temperature and pressure conditions. This innovative approach paves the way for synthesizing noroxymorphone via aerobic palladium-catalyzed continuous flow N-demethylation.
Another significant patent by Roberge outlines a method for preventing the plugging of a continuous-reaction channel system. This occurs due to by-products generated during continuous reactions. The invention entails the generation of ultrasonic waves traveling through the channel system and coupling these waves into the process fluids, effectively mitigating potential issues that arise during continuous flow processes.
