摘要: A variety of 3-aryl tetronic acids have been synthesized by an undirected, intermolecular C–H functionalization arenes with 3-diazofuran-2,4-dione. This methodology featured as a key step in the synthesis series naturally occurring 3-aryl-5-arylidene (pulvinates) from commercially available acid. Salient features pulvinic acid include one-step, stereoselective C5 arylidene group and single introduction C3 aryl substituent.
