A variety of 3-aryl tetronic acids 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 tetronic acids (pulvinates) from commercially available tetronic acid. Salient features of the pulvinic acid synthesis include a one-step,
通过使用3-重氮呋喃-2,4-二酮对芳烃进行无方向的CH-H分子间官能化反应,已经合成了多种3-芳基tetronic酸。该方法学是从可商购的tetronic酸合成一系列天然存在的3-芳基-5-芳基亚芳基tetronic酸(pulvinates)的关键步骤。戊酸合成的显着特征包括C5芳基的一步一步立体选择性合成和C3芳基取代基的一步导入。
