Reaction of alkynes with tetracarbonyl[methoxy(2,4-dimethoxyphenyl)carbene]chromium: A formal synthesis of 7-methoxyeleutherin

Article abstract of DOI:10.1080/00397910008087006

The reaction of alkynes with tetracarbonyl[methoxy(2,4-dimethoxyphenyl)carbene]-chromium, followed by oxidation, gives naphthoquinones as well as other cyclized products. This has been utilized in the preparation of (3) an intermediate in the synthesis of 7-methoxyeleutherin.
