Abstract

Cycloisomerizations of 1, n-enynes (n= 5, 6) catalyzed by transition metals are powerful tools for accessing complicated carbocycles.[1, 2] Such reactions have been intensively studied for many transition metals having diverse reaction mechanisms. Metal-catalyzed oxidative cyclizations of 1, n-enynes (n= 5, 6) are synthetically appealing because the product skeletons incorporate oxy or oxo functionalities,[3, 4] but there are fewer reported ...
