PROCESS FOR THE PREPARATION OF 2 ', 3'-DIDHIDRO-2', 3'-DIDESOXINUCLEOSIDOS PRO-PHARMACOS WITH ANTI-VIRAL ACTION

摘要

There are disclosed novel prodrugs of 2 min ,3 min -didehydro-2 min ,3 min -dideoxynucleosides, for example, of 2 min ,3 min -didehydro-2 min ,3 min -dideoxythymidine. The prodrugs are hydrolyzable under physiological conditions to yield compound which are useful as antiviral agents, especially as agents effective against the human immunodeficiency viruses (HIV).
