| Abstract: | Rhodium(I)-catalyzed 2 + 2 + 2] cycloadditions of sterically encumbered aryl-substituted ynamides with various diynes are described here. These cycloadditions provide the synthesis of an array of new chiral amide-substituted biaryls that can be useful in future chiral ligand designs. |
