SYNTHESIS OF SOME BIOLOGICALLY ACTIVE DERIVATIVES OF 2-HYDROXYMETHYL-5-HYDROXY-4H-PYRAN-4-ONE
Depending on reaction conditions, acylation of the phenolic and primary alcoholic group in 2-hydroxymethyl-5-hydroxy-4H-pyran-4-one leads to mono- or disubstituted products.Also described is acylation of the phenolic group in 2-chloromethyl- or 2-bromomethyl-5-hydroxy-4H-pyran-4-one as well as the nucleophilic replacement of the halogen by azide group.The prepared derivatives exhibit herbicidal and growth regulatory activity.
