Rhodium-catalyzed Enantioselective [2+2+2] Cycloaddition of Tosylamide-linked 5-Allenal and 5-Allenone with Internal Alkynes
It has been established that a cationic rhodium(I) BINAP complex catalyzes the enantioselective [2 + 2 + 2] cycloaddition of a tosylamide-linked 5-allenal and 5-allenone with internal alkynes, leading to bicyclic oxygen heterocycles.
