Phosphoramidate prodrug of nucleoside analogues, a pharmaceutical composition and applications of the phosphoramidate prodrug

The invention relates to phosphoramidate prodrug of nucleoside analogues, or stereoisomers of the phosphoramidate prodrug, or a mixture of the stereoisomers of the phosphoramidate prodrug, or pharmaceutically acceptable salts or solvates of the phosphoramidate prodrug, and applications in the preparation of medicine for preventing or treating hepatitis B virus (HBV) and/or human immunodeficiency virus (HIV) infection alone or in combination with other medicine. The anti-HBV activity of the compound of the invention is equivalent to that of tenofovir alafenamide fumarate (TAF), and the compoundof the invention has the anti-liver fibrosis effect, can help improve the therapeutic effect of patients, and has good safety important clinical significance.

Synthesis of highly functionalized diaryl ethers by copper-mediated O-arylation of phenols using trivalent arylbismuth reagents

Highly functionalized diaryl ethers were prepared by copper(II) acetate mediated O-arylation reaction of phenols using trivalent organobismuthanes. The reaction is performed under simple conditions and tolerates a wide diversity of functional groups on the phenol and on the organobismuth reagent. Substoichiometric amounts of catalyst can be used by performing the reaction under an oxygen atmosphere. The N-arylation of pyridones is also reported.
