Latest Patents

Allen Liu holds a patent for the "Process of making an alpha-anomer enriched 2-deoxy-2,2-difluoro-D-ribofuranosyl sulfonate and use thereof for making a beta nucleoside." This process involves preparing an alpha-anomer enriched 2-deoxy-2,2-difluoro-D-ribofuranosyl sulfonate, which serves as an intermediate in the synthesis of beta nucleosides, such as gemcitabine, a recognized anti-tumor agent. The method includes heating a beta-2-deoxy-2,2-difluoro-D-ribofuranosyl sulfonate to convert it into an alpha-anomer without the presence of a sulfonate salt. Additionally, an anomeric mixture can be dissolved in a water-solvent mixture and heated to produce a lactol, which can further be converted to the desired alpha-anomer enriched sulfonate.
