Intramolecular Pauson-Khand reactions of aromatic enynes

The synthesis of a series of O-alkenylated ethynylphenol derivatives and their NMO promoted intramolecular Pauson-Khand reactions are reported. The effects of substitution on both the alkene and alkyne moiety have been investigated.

Cycloisomerization between Aryl Enol Ether and Silylalkynes under Ruthenium Hydride Catalysis: Synthesis of 2,3-Disubstituted Benzofurans

Metal-catalyzed cycloisomerization reactions of 1,n-enynes have become conceptually and chemically attractive processes in the search for atom economy, which is a key subject of current research. However, metal-catalyzed cycloisomerization between aryl enol ether and silylalkynes has not been developed. The ruthenium hydride complex catalyzed cycloisomerization between aryl enol ether and silylalkynes is reported to give benzofurans having useful functional groups, vinyl and trimethylsilylmethyl, on the 2- and 3-positions, respectively.

Tandem Enyne Metathesis-Diels-Alder Reaction for Construction of Natural Product Frameworks

Enynes connected through aromatic rings are used as substrates for metathesis reactions. The reactivity of three ruthenium carbene complexes is compared. The resulting 1,3-dienes are suitable precursors of polycyclic structures via a Diels-Alder process.
