Several alkyl pyrone-5-carboxylates (coumalates) with alkyl and functionalized alkyl substituents at C4 and C6 have been prepared by a general route; their cycloadditions with electron-rich olefins have been carried out to provide aromatic and non-aromatic products, of potential value for natural products synthesis.
