title: Conformational specificity in photoinduced intramolecular 1,7-hydrogen abstraction of homonaphthoquinones with a spiro-linked dibenzocycloheptene ring
abstract: [reaction: see text] Irradiation of homonaphthoquinones with spiro-linked dibenzocycloheptene rings brings about the Norrish type II reaction to give polycyclic alcohols via a stereospecific 1,7-hydrogen abstraction of the less stable twist-boat conformer.
