The first total syntheses of sophoflavescenol (1), flavenochromane C (2), and citrusinol (3) were achieved. These three naturally occurring prenylated or prenyl-cyclized flavonoids have important biological activities such as cytotoxicity against some can
1H-NMR CHEMICAL SHIFT OF THE FLAVONOL 5-HYDROXY PROTON AS A CHARACTERIZATION OF 6- OR 8-ISOPRENOID SUBSTITUTION
