Structurally complex 2(5H)-furanones are potentially challenging targets for ring-closing metathesis (RCM). A hydrogen bonding-guided RCM strategy was developed in this study to provide 3-substituted and 3,4-disubstituted 2(5H)-furanones in moderate to high yields with broad functional group tolerance. A workup procedure using ethylenediamine-derived polyamines such as tetraethylenepentylamine was also established to effectively remove Ru residues in products.
