A tandem ring-closing metathesis/cross-metathesis procedure was devised for the synthesis of various pyrones. The reaction occurred with high regioselectivity and E stereocontrol of the lateral unsaturated chain. This process was applied to the synthesis of rugulactone, an inhibitor of the nuclear factor NF-κB according to a four-step sequence.
