Elaboration of the A ring of phomazarin by the Conrad-Limpach approach has been shown to be possible in the case of a protected hydroquinone substrate. However similar condensations using a suitably substituted naphthoquinone gave a lactam instead of the expected benzoquinolone. Attempts to annulate simplified models of the A-B rings with the appropriate diene have also been successful albeit in low

An attempt to confirm the structure proposed for phomazarin has been initiated by the synthesis of one of its degradation products. The methods chosen also resulted in the regiospecific elaboration of the B and C rings of the pigment and are applicable to eventual syntheses by convergent approaches.
