Gold(I) complexes containing monodentate PIII-ligands built upon methylated α-cyclodextrins have been synthesized and assessed in the cycloisomerization of 1,6-enynes, two of the reactions studied involving prochiral substrates. Their performance was compared with that of previously reported mononuclear and dinuclear α- and β-cyclodextrin-based AuI complexes. Enantiodiscrimination was found to be strongly dependent on the ability of the ligand to position metal-coordinated substrates inside the cyclodextrin core.

Platinum(II) complexes which combine six-membered N-heterocyclic carbene-containing metallacyclic units and monodentate chiral phosphines have been prepared. The key step of their synthesis is the intramolecular oxidative addition of N-2-iodobenzylimidazo

(Chemical Equation Presented) Efficient rhodium(I)-catalyzed cyclopropanation reactions of nitrogen-tethered 1,6-enynes to azabicyclo[4.1.0]heptenes are reported. Moreover, rhodium(I)-catalyzed tandem cycloisomerization and carbonylative [3+3+1] cycloaddition reactions of a cyclopropylenyne have been observed. 2010 American Chemical Society.

The skeletal reorganization of 1,6- and 1,7-enynes leading to 1-vinylcycloalkenes using Rh(II) as a catalyst is reported. Two possible isomers of 1-vinylcycloalkenes, type I and type II, can be obtained, the ratio of which are highly dependent on the subs
