experimental part, p. 4212 - 4217 (2010/07/05)
A rhodium-catalyzed cycloisomerization reaction of N-tethered 1,6-enynes with an intramolecular halogen shift has been developed, providing a useful process for the synthesis of stereo defined γ-butyrolactam and pyrrolidine derivatives in good to excellent yields. Effects of both electronic feature and steric structure of the substrates on the outcome of the reaction were investigated.

Three in one pot! Bicyclic cyclopentenones have been synthesized from enynes in alcohol in the presence of a rhodium catalyst through a newly developed auto-tandem catalytic reaction. This process combines three mechanistically distinctive reactions - an
Gold(I)-catalyzed intramolecular [4+2] cycloadditions of arylalkynes or 1,3-enynes with alkenes: Scope and mechanism

The cyclizations of enynes substituted at the alkyne gives products of formal [4+2] cyclization with Au(I) catalysts. 1,8-Dien-3-ynes cyclize by a 5-exo-dig pathway to form hydrindanes. 1,6-Enynes with an aryl ring at the alkyne give 2,3,9,9a-tetrahydro-1

The palladium-calalysed 'metallo-ene' step in a cyclisation/β-elimination reaction sequence has been shown to be suprafacial with respect to the olefinic component. This reaction has been applied to the synthesis of a trisubstituted exocyclic alkenyl pyrrolidine with complete stereocontrol.
