Twelve flavonoids with three hydroxy and four methoxy groups located at C-2', 3', 4', 5, 6, 6', 7 (1-4), C-2', 3', 4', 5, 6', 7, 8 (5), C-2', 3, 4', 5, 5', 6, 7 (6-11) and C-2', 3, 4', 5, 5', 7, 8 (12) were synthesized to confirm the structure of NAS-3 and to investigate the spectral properties of the hepta-oxygenated flavonoids. The methods used to prepare the tetra-oxygenated benzaldehydes (14-19) for the B ring moieties are also described.
