Article abstract of DOI:10.1021/jo00185a002

Structures proposed for trypethelone, O-methyltrypethelone, and O-methyl-8-methoxytrypethelone have been confirmed by synthesis.The required naphthoquinone substrates were prepared regiospecifically in one step by using vinylogous ketene acetals and then converted to the desired products essentially in a novel one-flask procedure.
