Definitions
- the present invention relates to a method for producing an acyloxypyranone compound, a method for producing an alkyne compound, and a method for producing a dihydrofuran compound, and in particular, starting from 6-hydroxy-2H-pyran-3 (6H) -one (hydroxypyranone)
- the present invention relates to a method for producing an intermediate of 4′-ethynyl-2 ′, 3′-didehydro-3′-deoxythymidine (4′-ethynyl d4T) as a raw material.
- 4'-ethynyl-2 ', 3'-didehydro-3'-deoxythymidine is a compound expected as a component of an acquired immunodeficiency syndrome (AIDS, AIDS) drug (For example, see Patent Document 1 and Patent Document 2).
- AIDS acquired immunodeficiency syndrome
