Latest Patents

One of Xiaohua Liu's latest patents is the "Asymmetrically catalyzed synthesis method of nitropyrazole amide compound." This invention provides a synthesis method for γ-nitropyrazole amide compounds through an asymmetrical catalyzing technique. The process utilizes a nitroalkane and an α,β-unsaturated pyrazole amide as raw materials. A complex formed by a chiral amine oxide with a rare earth metal compound serves as the catalyst, while a 4 Å molecular sieve acts as an additive. This method achieves a yield of over 99% and an enantiomeric excess greater than 99% ee. The catalytic system is advantageous due to its simple operation, mild reaction conditions, and compliance with green atomic economy, making it suitable for industrial applications.

Another significant patent is the "Intermediate for synthesizing paroxetine, method for preparing the same, and uses thereof." This invention details a method for preparing a paroxetine intermediate by reacting specific compounds in the presence of an organic base under the catalysis of a chiral amine oxide and a rare-earth metal compound. The method is designed to produce compounds with potential physiological activities.
