NEW METHODS FOR THE SYNTHESIS OF PHOSPHONO-δ-LACTONES

Abstract

Phosphono-δ-lactones are widely used as bioactive compounds, flame retardants, and polymer building blocks. Over the past years, new methods to access this heterocycle have been developed, some of them using innovative methodologies, like electrochemistry or photocatalysis. The current microreview covers selected methods over the past 5 years.
