Conformational Specificity in Photoinduced Intramolecular 1,7-Hydrogen Abstraction of Homonaphthoquinones with a Spiro-Linked Dibenzocycloheptene Ring
摘要:
[GRAPHICS]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.
