A variety of 3-aryl tetronicacids have been synthesized by an undirected, intermolecular C–H functionalization of arenes with 3-diazofuran-2,4-dione. This methodology featured as a key step in the synthesis of a series of naturally occurring 3-aryl-5-arylidene tetronicacids (pulvinates) from commercially available tetronicacid. Salient features of the pulvinic acidsynthesis include a one-step,
