title: Synthesis of a tricyclic mescaline analogue by catalytic C-H bond activation.
abstract: [reaction: see text] A tetrahydrobis(benzofuran) mescaline analogue has been prepared in six steps and 38% overall yield from (4'-O-methyl)methyl gallate. The key step in this synthesis is a tandem cyclization reaction via directed C[bond]H activation followed by olefin insertion.
