Abstract

Base-induced elimination of the dichlorocarbene adduct 8 of 9-methoxyphenanthrene (7) give rise to the formation of the phe-nanthrofuran 9. A mechanism involving a cyclopropene-vinyl-carbene rearrangement (10-11) followed by intramolecular insertion into the C-H bond of 11 is proposed for the transformation.
