A formal [3+3+1] reaction through gold(I)‐catalyzed enyne cycloisomerization of enyne‐methylenecyclopropanes and rhodium(I)‐catalyzed [6+1] reaction of vinylspiropentanes and CO has been developed to synthesize aza‐6/7 bicyclic compounds, hexahydrocyclohepta[c]pyridinones. DFT calculations ...
We report the first Rh 2 (II)-catalyzed asymmetric cycloisomerization of activated enynes to provide cyclopropane-fused tetra-hydropyridines in good yields and excellent enantioselectivities under mild conditions. The activated group, CHZ (Z is electron-withdrawing group (EWG)), in the enyne ...
In the case of alkene-tethered 1,6-allenyne, both 1,2- and 2,1-insertions of alkene into the Rh-C(sp(2)) bond of the five-membered rhodacyclic intermediate are plausible, and the resulting rhodium-alkyl intermediates will afford cycloisomerization products through reductive elimination. In ...

The Cu-catalyzed Mannich-type condensation was further extended to the synthesis of the glycinate-tethered dienyne and cyclopropylenyne, which were subjected to Rh-catalyzed cycloisomerizations to furnish bicyclic amino acids.doi:10.1016/j.tet.2007.07.105Yoshihiko Yamamoto...
