journal contribution
posted on 2006-09-01, 00:00 authored by Dirk Hildebrandt, Gerald DykerThe facile formation of the B and C ring of rac-desoxyequilenin and of a chrysenone derivative in just
one preparative step is demonstrated, applying a gold-catalyzed domino process, which involves a
benzopyrylium cation as the key intermediate and an intramolecular [3 + 2] cycloaddition as the key
step.
