Abstract
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
