charantia catalyzed the H2O2-dependent oxidative coupling of 7-hydroxy-4-methylcoumarin to form four new dimers (1–4) and two known ones (5, 6). The structures, including the absolute configurations of axiallychiral compounds, were unambiguously characterized by NMR spectroscopy, online HPLC-CD, and a variety of computational methods. Bioactive experiments demonstrated that compounds 1 and 2 had significant
