The Hauser-Kraus annulation of sulfonylphthalide with Morita-Baylis-Hillman (MBH) adducts nitroalkenes provides access to phenanthrenes and naphthoquinone fused dihydrobenzoxepines. H-K results in naphthoquinones bearing a key alcohol group protected form, which leads tetracyclic oxepines upon reaction formaldehyde. These alcohols yield functionalized via oxidation [3 + 3] β-ketoesters.
