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
