Brønsted acid-mediated cyclizations of siloxyalkynes with simple arenes and
alkenes afforded substituted tetralone and cyclohexenone derivatives. A wide
range of substrates can be employed in these carbocyclizations.

A mild, palladium-catalyzed intramolecular oxidative alkylation of various
ζ-alkenyl β-diketones and ζ-alkenyl β-keto esters in the presence of CuCl2
at room temperature formed the corresponding 2-cyclohexenones in high yield.

An efficient and regioselective Yb(OTf)3-promoted palladium-catalyzed
oxidative cyclization of γ-heteroalkenyl β-keto amides has been developed. Under
simple aerobic condition, various six-, seven-, and eight-membered-ring N-
and O-heterocycles were obtained in excellent yield.
