An efficient gold-catalyzed ring-expansion reaction of enyne-lactones to form 2-oxoninonium intermediates is reported. The 2-oxoninonium generated in this work could undergo further 6π electrocyclization and aromatization reaction to produce different aromatic compounds.
Generation of o-quinodimethanes (o-QDMs) from benzo[c]oxepines and the synthetic application for polysubstituted tetrahydronaphthalenes

supporting information, p. 7687 - 7694 (2015/09/07)
A novel method for the generation of o-quinodimethane (o-QDM) intermediates is reported using a mild and efficient base-promoted ring-opening of benzo[c]oxepines. Among the benzo[c]oxepines studied, indanone containing analogues demonstrated the greatest
Synthesis of substituted naphthalenes from α-substituted ketones and 1,2-bis(halomethyl)benzenes including a rearrangement aromatization of benzo[c]oxepine

An efficient and practical method for the synthesis of cyano, sulfonyl and phosphoryl substituted naphthalene derivatives via the rearrangement aromatization of benzo[c]oxepine has been developed. The system holds the advantages of metal catalysts free, and mild reaction conditions.
Regioselective synthesis of poly-substituted naphthalenes via a Pd-catalyzed cyclization of modified Baylis-Hillman adducts: Selective 6-endo Heck reaction and an aerobic oxidation cascade
Kim, Se Hee,Lee, Sangku,Lee, Hyun Seung,Kim, Jae Nyoung
experimental part, p. 6305 - 6309 (2011/01/04)
Poly-substituted naphthalenes were synthesized via a Pd-catalyzed cyclization of modified Baylis-Hillman adducts having an o-bromophenyl acetonitrile moiety at the secondary position, in reasonable yields. The reaction involved a sequential 6-endo Heck re
Construction of a tetracyclic butterfly-like scaffold: Palladium-catalyzed heck/arylation cascade

Controlled carbopalladation: Only slight changes in the starting material (see scheme) resulted in rather different compounds in palladium-catalyzed domino reactions. A novel tetracyclic butterfly-like scaffold was constructed in a one-pot reaction via the Pd-catalyzed 5-exo-trig carbopalladation and arylation cascade in high yield.
