Method for producing acyloxypyranone compound, method for producing alkyne compound, and method for producing dihydrofuran compound |
| abstract |
An acyloxypyranone compound represented by formula (II) (wherein R1 represents an acyl group) is produced by causing an acylating agent and a hydrolase to act on hydroxypyranone represented by formula (I) in a hydrous organic solvent; an alkyne compound represented by formula (IV) is produced by causing an acetylene organic metal compound represented by formula (III) (wherein R2 represents a hydrogen atom or a trisubstituted silyl group, and M represents an alkali metal atom, aluminum or magnesium monohalide) and a coordinating additive to act on an acyloxypyranone compound represented by formula (II); and a dihydrofuran compound represented by formula (V) is produced by acid hydrolyzing an alkyne compound represented by formula (IV). |
