His work focuses on innovative methods for preparing antiviral calanolide compounds, which have potential applications in medicine.

Latest Patents

Yuan's latest patents include methods for preparing 2,2-dimethyl-5-acyloxy-10-propyl-2H,8H-benzo[1,2-b:3,4-b']dipyran-8-one and 2,2-dimethyl-5-hydroxy-10-propyl-2H,8H-benzo[1,2-b:3,4-b']dipyran-8-one. These compounds serve as intermediates for synthesizing antiviral calanolide compounds. For instance, the Fries rearrangement on compound 5 or the Friedel-Crafts reaction on compound 6 yields an intermediate that can be converted to (+)-calanolide A and (−)-calanolide B. Additionally, the coupling of compound 6 with the appropriate chiral molecule under Mitsunobu or nucleophilic displacement leads to the asymmetric synthesis of these antiviral compounds.
