摘要: There are disclosed novel processes for producing 2',3'-dideoxy-2'3'-didehydronucleosides, for example, 2',3'-dideoxy-2',3'-didehydrothymidine in high yields and on a large scale. The compounds so-produced are useful as antiviral agents, especially as agents effective against the human immunodeficiency viruses (HIV).
