Latest Patents

Long Tang'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, leading to the production of intermediate II. This is followed by a reaction between intermediate II and 2,4,6-trichlorobenzoyl chloride, and a condensation reaction with rapamycin to produce intermediate III. The final step involves using sulfuric acid to remove a protecting group from intermediate III, yielding temsirolimus.

The second patent, "Method for synthesizing temsirolimus," describes a similar process but utilizes a substituted boric acid for the protection of 2,2-dimethylol propionic acid. The subsequent steps mirror those of the first patent, culminating in the synthesis of temsirolimus through the removal of a protecting group using a diol.
