Latest Patents

Jinzhou Li's latest patents include two methods for synthesizing temsirolimus. The first patent, titled "Method for preparing temsirolimus," outlines a process that involves using a substituted aromatic aldehyde to protect 2,2-dimethylol propionic acid to produce an intermediate. This intermediate undergoes a reaction with 2,4,6-trichlorobenzoyl chloride, followed by a condensation reaction with rapamycin to yield another intermediate. Finally, sulfuric acid is used to remove the protecting group, resulting in temsirolimus. The second patent, "Method for synthesizing temsirolimus," employs a substituted boric acid for protection instead of an aromatic aldehyde, leading to a similar series of reactions that culminate in the production of temsirolimus.
