A new route to several medium ring heterocycle and carbocycle fused naphthalene derivatives of potential medicinal importance has been developed involving tandem applications of Claisen rearrangement and ring-closing diene metathesis as key steps. Copyright Taylor & Francis Group, LLC.
Naphthalene-based calixarenes: Unusual regiochemistry of a Friedel-Crafts alkylation
Shorthill, Berkeley J.,Glass, Timothy E.
, p. 577 - 579 (2001)
(Matrix presented) In the pursuit of naphthalene-based calixarenes, a Friedel-Crafts alkylation with unusual regiochemistry was observed. Treatment of carbinol 14 with catalytic triflic acid was expected to produced calixarenes of the class represented by 16. Instead, the major product was cyclic trimer 15, in which alkylation of each naphthalene ring occurred at the electronically deactivated position. The structure of compound 15 was assigned by 2-D NMR studies.
An expedient synthesis of bis-fused benzofuran and a two-directional ring- closing metathesis for the synthesis of bisbenzoxepines and bisbenzoxocines

Synthesis of bis-fused benzofuran derivatives by the implementation of palladium-mediated intramolecular cyclization is described. To our knowledge, this is the first report of the synthesis of bis-fused benzofuran by this protocol. Bisbenzoxepine and bis
