Abstract
Anodic oxidation of the model bilindione (1) at platinum electrodes in the presence of methanol gives a good yield of the 15,16-dimethoxybilindione (3). With nickel(II) acetate, this compound gives the chelate (6) which fragments upon treatment with acid to afford the tripyrrinone aldehyde (2) via the vinyl ether (8). When the metal-free 15,16-dimethoxybilindione (3) is treated with aqueous acid the same tripyrrinone aldehyde (2) together with the parent bilindione (1) are obtained.
