The chemistry of antimicrobially active 1-hydroxy-2-pyridones

The unsaturated δ-keto esters obtained by condensation of acid chlorides with esters of di- or trialkyl-acrylic acids can be cyclized with hydroxylamine to yield 1-hydroxy-2-pyridones. However, in many cases a two-steps synthesis may be of advantage in preparative respect, the ketoesters being cyclized to 2-pyrones, which then are reacted with hydroxylamine in the presence of certain bases to give. The hydroxy-pyridones show pronounced antifungal activity in vitro as well as in experimental guinea pig dermatophytosis.
