Abstract
Abstractα,β-Unsaturated δ-lactones are structural motifs found in diverse pharmacologically active natural products. In fact, the unsaturated lactone is often responsible for the biological activity. Herein, we report a new approach for the syntheses of (R)-argentilactone and (R)-goniothalamin based on a photoredox intermolecular iodolactonization mediated by a photoredox process. This new approach, already employed in our research group, stands as a new methodology to achieve several natural products containing α,β-unsaturated δ-lactones.
