Cyclization of 4‑Phenoxy-2-coumarins and 2‑Pyrones via a Double C–H Activation [PDF]
, 2016 Aryl–heteroaryl coupling via double C–H activation is a powerful transformation that avoids the installation of activating groups. A double C–H activation of privileged biological scaffolds, 2-coumarins and 2-pyrones, is reported.

Journal of the Mexican Chemical SocietyAbstract. Here we report the first biomonitored synthesis of pyrones in the search for molecules with antimicrobial action against pathogenic bacteria and fungi. Pyrones were synthesized from methyl acetoacetate pyrone rings followed by deacetylation, methylation, and aldol condensation reactions to obtain styrylpyrones with yields between 39 and 93 %.
